What Are My Genetic Genealogy Goals?

I’ve been spending a lot of time—a real lot of time—working with my Ancestry DNA, FTDNA, and GEDmatch results, working through my match lists, compiling data, and, where I can, identifying my most recent common ancestors with various matches. It’s a great deal of work. And most of the time I feel like I’m flailing about, trying to swim in water that’s really too deep for my abilities.

As I was traversing a match’s GEDCOM file searching for a common surname—unsuccessfully, I might add—it occurred to me to wonder why I was doing so. Just what did I hope to gain from all this work?

It’s common online to see folks trying to identify relatives in order to identify their or a relative’s birth family. That’s not my situation. I know who my parents, grandparents, and great grandparents are—and my DNA matches confirm this.

So, why am I spending so much time analyzing my results? What do I get out of it? I took the test for fun. I thought it would be interesting to see my ethnicity results, maybe find some cousins. I’ve already done so much research to build the “paper trail,” I didn’t really consider that it might be useful otherwise.

But recently I’ve been spending significantly more time working with the DNA results, than I have been researching. Maybe it’s time to stop and consider whether that’s a productive use of my time.

What do I want to get out of it?

Here’s that I’ve been able to come up with so far.

1. I want to use genetic genealogy to confirm my research.

Not particularly exciting and rather obvious, but a true and useful goal. My DNA matches have become another piece of source data to add to a proof argument. The fact that I share DNA with other descendants of Philip Hoover and Hannah Thomas of Armstrong County strengthens my assertion that my ancestor Christian Hoover was their eldest son. As more matches come in which share DNA with their descendants—or those of their ancestors—the stronger my argument will grow.

2. I want to “ancestor map my chromosomes.”

Since I know the majority of my ancestry back six generations, and a number of lines back even further, sounds like a simple thing to do, right?  Uh huh. Wouldn’t that be nice? There are actually several factors that complicate this process.

First, in order to find how you and a DNA match are related, you need to compare ancestors. Sometimes it’s as easy as finding a shaking leaf on Ancestry. It’s more common, however, to find no family tree to examine, a private family tree, or a tree with only couple of generations—all marked “private”—with no names or dates. Somewhat less than useful. Furthermore, when you contact matches hoping to collaborate, you get no response.

Second, my ancestors on both sides of my family tree arrived in Pennsylvania, decided it was a good place to live, and then never left. Although this really helps with the document research, it complicates the DNA research. You see, they not only stayed, but they married. Then their descendants intermarried. So, finding how I match that 4th-6th cousin prospect is not always as simple as locating the common surname in a family tree. Occasionally, there are multiple common ancestors. Which one (or more) is the reason for the match?

Which brings us to the next difficulty—Ancestry’s total lack of useful tools to analyze the actual DNA. At most, you can identify the overall amount to DNA you share and the number of segments. Because there is no means of identifying segment or chromosome information; there is no method to triangulate your matches. You can’t determine whether the DNA you share with several matches is actually the same segment on the same chromosome—or that they share that same DNA between them, too.

To actually use Ancestry DNA results for more than just guessing, you need to upload it to GEDmatch or Family Tree DNA so that you can access segment and chromosome data. You can upload to both for free—although to use FTDNA’s tools, you’ll need to pay a small fee. It was $19 when I did it and well worth the price.

Several of my Ancestry matches have already uploaded to both places. Because they’ve done so, I was able to identify the specific segments we share from our common ancestors. It’s cool to see that I likely got about 30 centimorgans (cM) of DNA on chromosome 16 from my 4x great grandfather George Walker of Boggs Township, Centre County, Pennsylvania. A shorter segment on chromosome 16 may have come from his in-laws, Andrew and Catharine Margaret (Fetter Fetzer) Walker.1

3. Break down some genealogy brick walls.

This one is the trickiest of my three goals. Christian Hoover was a brick wall ancestor for some time. Research, however, pointed to a possible location and family. DNA, so far, has been supporting that conclusion. More on that in another post.

Another brick wall ancestor is Jefferson Force. I believe he was orphaned at a young age, possibly as early as age ten. My research to date has not yielded much. I would like very much to identify his parents. Identifiable DNA matches between other Force descendants to some of Jefferson’s descendants might provide other avenues to explore. Jefferson’s parents would be my 4x great grandparents. This is pushing the limits of usable DNA information as 25% to 50% of 4th cousins share no DNA. Someone of my generation would likely be my 5th cousin, making it even a bit more unlikely a share DNA with any given 5th cousin.

The Plan

So now that I’ve identified some goals for using DNA testing in my genealogy, it’s time to come up with a plan and action items. What exactly do I need to do to accomplish them? More testing will likely be required. Any aunts, uncles, or cousins out there who want to volunteer to take a DNA test?

My Genetic Communities

Several weeks ago, Ancestry released their newest tool: Genetic Communities. These communities are based on some pretty cool work with the DNA of millions of AncestryDNA test-takers.  This work was published in Nature Communications. You can read Ancestry’s paper “Clustering of 770,000 genomes reveals post-colonial population structure of North America” for more information. (It’s neat stuff!)

After the tool was revealed, there were a lot of great articles explaining it, how it works and how to use it, including:

(These blogs are good sources for other information on genetic genealogy and DNA testing, too!)

My Genetic Communities

My genetic communities were exactly what I would have expected from my research. I’m part of the Settlers of Colonial Pennsylvania and its two subgroups, Settlers of Central Pennsylvania and Settlers of the Poconos & New Jersey. The subgroups even match up to my paternal and maternal lines.

My Genetic Communities

Although I was hoping to see some European communities,1 I’m not disappointed in my results. There were no surprises that could launch new and exciting areas to research, but that’s okay. There is great value in consistency in genealogical research. My DNA results have—so far—been supporting my research-based conclusions.

My Genetic Communities Accuracy

Ancestry’s confidence that I genetically belong in this community is 95%. This is a very good thing. It means that my work is most likely valid and correct. There may be tweaks that need to be made the farther back I go, connections to re-evaluate, but overall the foundation is sound. I am following the right paths.

One thing I’ve noticed is that the communities are not static. The Settlers of Colonial Pennsylvania included only Pennsylvania in the original release, but now includes all of Pennsylvania and portions of Ohio.

Colonial PA Settlers map comparison

This demonstrates, I believe, later migration paths of descendants of those early Pennsylvania settlers as they left eastern and central Pennsylvania. The article in Nature Communications includes a graphic that visually shows some of this migration by showing where the “Pennsylvania community” lived 3-9 generations ago.

So, it’s possible that as more people test—especially non North Americans—these communities will be refined even further and I just may get to see that Scottish community I was hoping for.

Friday Find: Is This Our Christopher Hocker?

I recently came across a reference to a Christopher Hocker who was living in Ohio in the early 1800s. As you recall, Johann George Hacker’s son Christopher was allegedly “of a rather headstrong disposition; he left his wife here in Montgomery county and went to Ohio, lived and married there a second time.”1

In Pennsylvania

Christopher was born about 1772 in Whitemarsh Township, Montgomery County, Pennsylvania, son of Johann George and Anna Margaretha (Weidman) Hacker.2 He married Catharine Daub, daughter of Henry and Christianna (Wohlfarth) Daub,  10 April 1792 at Saint Michael’s Lutheran Church in Germantown.3

The couple lived in Whitemarsh Township until about 1800. In 1805, he purchased a tavern and acreage from his father-in-law in Sandy Run.4 According to deed records, Christopher (Innkeeper) purchased a lot in Whitemarsh Township from the daughters of Jacob Edge on 1 April 1807.5

About 1808, Christopher apparently ran into financial troubles. On 5 April 1808, Christopher (Farmer) and Catharine Hocker sold this land to Daniel Hitner.6 He also gave up the tavern to assignees John Wentz, George Price, and Samuel Maulsby.7 According to family legend, Christopher found himself in debt and fled to Ohio.

I haven’t been able to track Christopher down in Ohio. His son George, who later returned to Whitemarsh Township, was said to have been born there in 1814. And we know Christopher was still alive as of 1821 as he was named as one of the surviving children in his father’s estate files.8

So, just where did Christopher go?

In Ohio

Maybe he was living on Licking Creek in Falls Township, Muskingum County, Ohio. I found reference to a Christopher Hocker living there in a Cumberland County Historical Society journal article about Jacob Fought, a Carlisle tavern keeper. About Christopher, it says:

“In April 1814, Christopher Hocker, who lived on Licking Creek in Falls Township, Muskingum Counry, Ohio…hired a young man, Asher Nichols, to help take the horses to Philadelphia… Their eastward trip passed through Carlisle, Pennsylvania where they arrived on the sixth or seventh of February 1815. In Carlisle, they stayed at Jacob Fought’s inn, Sign of the Plough and Harrow, located only two blocks from the town center where the courthouse, market, and two established churches were.

On 9 February 1815, Nichols left the inn and stable along with Hocker’s two horses, and without Hocker’s permission. He arrived at Hummelstown, probably the town by that name near Harrisburg. Nichols was found and brought back to Carlisle to stand trial for horse stealing. A great effort was made to seek evidence for this serious accusation. This included sending prosecution and defense interrogatories to the Muskingum County court, which deposed four key Ohio witnesses.

Asher Nichols was indicted on a charge of larceny, for horse stealing, on oath of Christopher Hocker, in the summer of 1815… Asher Nichols was found guilty and sentenced to hard labor. The bills or taxes for witnesses and the docket session findings do not state the term of the sentence.”9

This is the first reference I’ve found to a Christopher Hocker in a specific location in Ohio at a time when Johann George’s son was alleged to have been there. 1814, the year Christopher’s son George was said to have been born in Ohio. This passage also provides several sources to follow-up with—Cumberland County court records and Muskingum County court records—regarding the theft of Christopher’s horses in Carlisle.

Time to get crackin’.

Wordless Wednesday: George W. Houdeshell Family

George Houdeshell Family

George Houdeshell Family, circa mid 1920s

George W. Houdeshell married Lovina Caroline Force on 20 June 1890. Between then and 1914, they had 12 children, ten of whom survived to adulthood. This Wordless Wednesday features their family photo.

George and Lovina are sitting. One the left are sons Millard Franklin and William Arthur with daughter Martha Rebecca in front of them. The youngest daughter is on the right, Georgia Caroline. I do not know the exact identities of the four women in the back row—do you?—but most likely includes four of the following daughters: Thelma Mae, Carrie Edna, Anna Belle (if taken before 3 September 1924), Ida Rachel, Wilhelmina L., and/or Nora Melinda.

William Bonnington (c1816-1885) 52 Ancestors in 52 Weeks

William Bonnington, my four times great grandfather, was born about 1816 most likely in Bowden, Roxburghshire, Scotland.1 He was the son of Robert and Agnes (Inglis) Bonnington.2 He died 11 June 1885 in his brother’s house in Bowden.3

About 1838, he married Margaret Purves4 (or Fairborn).5 She was born about 1821 and died between 1844 and 1847. William married for the second time on 9 July 1847 in Melrose, Scotland to Mary Reavely.6 She was born about 1825 in Galashiels, Selkirkshire, daughter of Mark and Margareth (Paterson) Reavely, and died 21 April 1855 in Newington and Grange, Edinburgh.7 After her death, William married for the third time to Elizabeth Thomson on 16 June 1857 in St. Boswell’s Parish, Roxburghshire.8 Elizabeth was born about 1803, daughter of James and Janet (Goodfellow) Thomson, and died 15 November 1880 in the district of Bathgate.9

William worked as a joiner, a carpenter, and apparently moved with his work. In 1841, he can be found in the census for Galashiels, Selkirkshire.10 By 1851, he and family were in Ladhope, Melrose, Roxburghshire.11 Ten years later, the family was in Colinton, Edinburgh, Midlothian.12 He and third wife Elizabeth, as well as his daughter Isabella, were in Ilkley, Yorkshire, England in 1871.13 By 1881, William was living alone with a domestic in Bathgate, Linlithgow.14

William and Margaret (Purves) Bonnington had children:

  1. Anne Bonnington was born 5 May 1839 in Galashiels and likely died before 1851.
  2. Robert Bonnington was born 30 May 1841 in Galashiels and may have died prior to 1851.
  3. Peter Purvis Bonnington was born about 1844 and died 16 September 1891 of Phthisis Pulmonalis, a.k.a. Tuberculosis, in Lasswade Parish, Edinburgh. He married Elizabeth Buchanan on 17 June 1864 in Colinton.

William and Mary (Reavely) Bonnington had children:

  1. Margaret Bonnington was born about 1849 in Galashiels and died of Typhoid Fever on 23 December 1883 in Selkirk, Selkirkshire. She was a lady’s maid.
  2. Agnes Bonnington was born about 1850 in Galashiels and died sometime before 1855.
  3. Isabella Bonnington was born 16 February 1855 in Edinburgh, Midlothian. She was living with her father and step-mother in Ilkley in 1871, but no more is known about her after that time.

52 ancestors in 52 weeks

This post is part of a blogging challenge entitled 52 Ancestors in 52 Weeks, created by Amy Crow of No Story Too Small in 2014. Participants were to write about one ancestor every week. I’m revisiting this challenge for 2017. This is my thirteenth 52 Ancestors post, and a make-up post for week twelve.

James Smith (c1812-1856) 52 Ancestors in 52 Weeks

James Smith, my three times great grandfather, was born about 1812 in Whitburn, Linlithgow, Scotland1 to Thomas and Agnes (Nimmo) Smith and died on 8 February 1856 at age 44 in Whitburn.2 He was an “engineer,” a.k.a. engine worker, who worked in the coal mines.

On 25 December 1840, he married Isabella Aitken, daughter of William Aitken and Marion Brown of Lanark, Scotland.3 Isabella was born 27 February 1816 in Carnwath4 and died 1 December 1856 in Whitburn.5 Both she and James were buried in the Whitburn church yard.

On Sunday, 6 June 1841, the couple was living with Isabella’s parents at Auchengray in Carnwath parish.6 William and his son John were wrights, son-in-law George Tweedie a laborer, and son-in-law William Smith an ironstone miner.

By 30 March 1851, James and Isabella and their children were living at Crossroads in the parish of Whitburn in Linlithgow.7 They had apparently moved there by 1844 as all their childrens’ birthplaces are listed as Whitburn.

1856 was a terrible year for Thomas, Marion and William Smith, James and Isabella’s three children. After the death of their parents in February and December, they likely went to live with James’ brother and sister: William and Margaret. Marion died 11 May 18578 of hydrocephalus, likely acquired hydrocephalus caused by an injury, infection or tumor. Thomas and William can be found in Uncle William’s household in Whitburn in 1861.9

Thomas remained in Fauldhouse until his death in 1909. William became a ship’s engineer and travelled abroad, eventually marrying in Edinburgh and emigrating to the United States. He filed an intention to become a naturalized American citizen on 20 September 1886 in Berks County and became a citizen on 12 January 1893 at Harrisburg.10

James and Isabella (Aitken) Smith had children:

  1.  Thomas Smith was born circa 1844 and 9 May 1909, Fauldhouse, Greenburn, Whitburn parish. He married married Jane Bryce.
  2. Marion Smith was born circa 1846 and died 11 May 1857, Greenburn, Whitburn parish.
  3. William Smith (25 Sep 1851—23 Feb 1905, Harrisburg, Pennsylvania), married Eliza Craig Bennington, 12 December 1882, Uphill parish, Linlithgow

Jefferson Force (1833-1910) 52 Ancestors in 52 Weeks

My 3x great grandfather Jefferson Force’s ancestry remains a mystery. He was born 9 December 1833 in Centre County, Pennsylvania and died 20 October 1910 in Pine Glen.1 He married Susan L. Mulhollan, daughter of John and Emily (Boileau) Mulhollan, on 22 March 1857.2 His obituary reads:

“Died at his home in Pine Glen on Thursday, October 20th, Jefferson Force, a well known and respected citizen of that place, aged 76 years, 10 months and 11 days. During the Civil War, he was drafted in 1864 and received an honorable discharge in 1865. He was married to Susan Mulholland in 1857, with whom he spent a long and happy life. Mr Force was a charter member of Messiah Church, of that place and always remained steadfast to the church of his choice and served its teachings. He leaves a large circle of friends to mourn his loss. Funeral services were conducted by Rev. E.A. Meredith.”3

He enlisted in the Civil War on 20 December 1864 and mustered out 17 July 1865 at Alexandria, Virginia. He served in Company E of the 45th Pennsylvania Infantry Volunteers, 1st Brigade, 1st Division.4 During this period the regiment was involved in the advance on Richmond, Virginia, the Battle of Cold Harbor, the siege of Petersburg, the Battle of Chaffin’s farm, and the Appomattox campaign.5 Jefferson apparently was not wounded during the war, or at least not enough to impact his health.6

After the war, Jefferson lived and worked in Pine Glen, Centre County, Pennsylvania, as a house plasterer and farmer.7 Between 1857 and 1884, Jefferson and Susan had 14 children, five of whom died before 1900—nine daughters and five sons.

It’s been suggested to me that Jefferson was the son of Isaac and Polly (___) Force, who both died in the 1840s based on a Bible owned by Mrs. Agnes E. Shope. I have yet to find evidence to prove this supposition. A number of young Force children—including Martin and Agnes—can be found in a variety of non-Force-led households in the 1850 census enumeration for Centre County, indicating that they were most likely orphaned.

Agnes was born 8 April 1839 and may have been Jefferson’s sister. She named two of her sons Jefferson T. Shope and Martin V. Shope—both names of Centre County Force men. Jefferson also named a daughter Agnes E., perhaps after Mrs. Shope. She lived in Milesburg, Centre County and died in 1922. Martin V. Force (12 Dec 1835-28 May 1902) lived in Pine Glen and was Jefferson’s neighbor.

Jefferson and Susan (Mulhollan) Force had the following children:

  1. Wilhelmina Susan Force (29 Oct 1857-5 Nov 1921), married Robert Askey
  2. Catharine E. Force (13 Sep 1859-9 Mar 1899), married Albert Gilmore
  3. Hannah M. Force (1 Sep 1861-1 May 1938), married Johnson Watson
  4. Agnes E. Force (1 Aug 1863-16 Jul 1936), married John Thomas Fye
  5. Carrie Amanda Force (23 Aug 1865-3 May 1932), married William Henry Meeker
  6. Martin Luther Force (6 Feb 1868-23 May 1945), married Delilah N. Hamilton
  7. John C. Force (16 Jan 1870-27 Aug 1890)
  8. Lovina Caroline Force (28 Jan 1872-28 Oct 1964), married George W. Youdeshell
  9. Mary Alice Force (28 Jun 1873-12 Oct 1913), married Richard Whiles
  10. Martha Ellen Force (9 May 1875-10 Aug 1934), married Jacob Whiles, Wilson R. Smeal
  11. Lucy Malinda Force (26 Sep 1876-Mar 1960), married William Emetic, John G. Kein/King
  12. George W. Force (6 Jan 1878-10 Jan 1878)
  13. William E. Force (14 Sep 1883-9 Oct 1883)
  14. Albert M. Force (4 Sep 1884-5 Sep 1884)

Jefferson and Susan are my 3x great grandparents.

Henry Jones (1776-1854) 52 Ancestors in 52 Weeks

Perhaps not so surprisingly, I’ve fallen behind on my 52 ancestors posts. I’m hoping to catch up. Here’s a short one to start me off.

Henry Jones was born 15 July 1776 in Hilltown Township and died 10 December 1854 in Milford Township, both in Bucks County, Pennsylvania.1 He was buried in Christ Church cemetery in Trumbauersville. He was the son of Edward and Rachel (Lewis) Jones.2

Henry married Martha Bartleson by 1806.3 They lived in Milford Township, Bucks County, Pennsylvania where Henry was a farmer and carpenter. Martha died prior to 1 June 1830.

Henry and Martha (Bartleson) Jones had children:

  1. Levi Jones (c1807-bef 1870), married Catharine (Rhoads?)
  2. Rachael Jones (5 Mar 1809-10 Sep 1897), married John Witmer
  3. William Jones (c1811-23 Aug 1899), married Mrs. Hedrick and Catharine “Kate” Hartzell
  4. Mary Ann Jones (c1813-?), married Samuel Gilmore
  5. Lewis Jones (10 Nov 1815-21 Nov 1900), married Lydia Frederick
  6. Eliza Jones (c1817-c1849), married Wilson Davis
  7. Matilda Jones (? 1819-?)
  8. Isaac Bartleson Jones (11 Jan 1820-22 Apr 1892), married Sarah Senderling
  9. Henry Jones (12 Apr 1822-22 May 1893), married Peninah Shive
  10. Abel Jones (1 Feb 1824-27 Aug 1853)
  11. John Jones (c1826-?)
  12. Oliver Bartleson Jones (16 Aug 1829-4 Jan 1858), married Mary Elizabeth Bibighaus

Henry and Martha are my 5 times great grandparents.

Philip Hoover (1802-1882) 52 Ancestors in 52 Weeks

I’ve written extensively about my ancestor Christian Hoover and the search for his family. Now that I’ve got another piece of evidence that his parents were Philip Hoover and Hannah Thomas, I thought I’d write about them.

Philip Hoover was born about 1802, most likely on his father’s property on Plum Creek in Armstrong County.1  He was the third son and fourth child of Christian and Barbara (Harmon) Hoover. He died in May 1882 in Burlingame Township, Osage County, Kansas.2

Philip Hoover land survey

1820 Survey for Plum Creek Township land

About 1820, Philip married Hannah Thomas, daughter of John and Margaretta (Mackin) Thomas. She was born 14 July 1802 in Armstrong County and died 16 August 1880 in Burlingame Township.3  Hannah’s sister Sarah had married Samuel Hoover, Philip’s eldest brother, several years earlier. They lived in Plum Creek Township where Philip was a farmer.

On 21 August 1820, Philip had 73 acres surveyed.4 The survey was returned 28 June 1825. Philip sold this land on 3 February 1826.5 When his father died in 1850, Philip received land from his estate. He sold this land in a series of transactions in January 1876 and April 1877 before he and his wife headed west with his son Jacob and his family. Philip and Hannah both died in Burlingame several years later. Jacob and his family continued moving west, finally settling in Grays Harbor County in Washington by 1889.6

Philip Hoover 1850 census household

Philip Hoover 1850 census household

Based on census records, Philip and Hannah (Thomas) Hoover had children, born in Armstrong County:

  1. Christopher Hoover was born circa 1821 and died 1 October 1887, Covington Township, Clearfield County, Pennsylvania. He married Caroline Kinnard, also of Armstrong County. She was born about 1830 and died 11 February 1877 in Covington Township.
  2. Mary Ann Hoover was born 22 Nov 1825. She may have married a Fisher.
  3. John Thomas Hoover was born 4 November 1827.
  4. Margaret Hoover was born 1831. She married Stewart Davis Pitt.
  5. Barbara Hoover was born 1833. She may have married a Gibson.
  6. William Hoover was born 1835.
  7. Jacob Hoover was born 8 February 1846 and died 14 September 1909 in Aberdeen, Grays Harbor County, Washington. He married Julia Ann Rupert in Pennsylvania.
  8. Ralston Hoover was born 1839 and died 13 June 1862 at Baltimore Cross Roads in Virginia as a result of injuries sustained during fighting in battle during the Civil War.
  9. Sarah Hoover was born 1842 and died 1917. She married Henry Blystone on 28 March 1860.
  10. Samuel M. Hoover was born 1845.

52 ancestors in 52 weeks

This post is part of a blogging challenge entitled 52 Ancestors in 52 Weeks, created by Amy Crow of No Story Too Small in 2014. Participants were to write about one ancestor every week. I’m revisiting this challenge for 2017. This is my ninth 52 Ancestors post, part of week eight.

Ethnicity Estimate Comparisons How Does Family Tree DNA compare to Ancestry?

When I saw the recent announcement that Family Tree DNA was now accepting Ancestry V2 DNA uploads for autosomal transfer, I was excited, to say the least. I’ve been waiting impatiently for this since I did the testing last summer. So, I immediately uploaded my raw DNA. Here are my initial thoughts after trying it out.

Looking through my matches, I was surprised how many I recognized from my match lists from Ancestry. I’ve already identified the common ancestor for some of them. However, there are plenty that I still need to sort through to try to make that determination. As on Ancestry, many do not have pedigree information associated with their account. So, if I’m to determine how we match, I’ll need to make use of common matches.

I found the chromosome browser tool to be pretty cool. It’s one of the reasons I wanted to use Family Tree DNA. I’m a visual person, so a tool like this is really helpful to aid my understanding. Now I need to study up on segment matching so I actually know what I’m doing!

When I checked today, my ethnic origins had finished processing. I know the experts recommend taking ethnicity estimates with a grain of salt (or the whole darn salt shaker), but given how close the Ancestry estimates were to the estimate I made from my pedigree, I wasn’t expecting anything different on FTDNA. Boy, was I surprised!

According to Ancestry, my ethnic makeup looks something like this:

Ethnicity Chart

Figure 1: Ancestry’s Ethnicity estimate

According to Family Tree DNA, it looks more like this:

FTDNA Ethnicity

Figure 2: Family Tree DNA’s Ethnicity estimate

Surprise!

Here’s a comparison of the three estimates I’ve got in table form.

Region AncestryDNA Pedigree FTDNA
Western Europe 63% 73.72% 9%
Ireland 16% 15.6%
Scandinavia 5% 3.12% 58%
Great Britain 4% 1.56%
Italy/Greece 2%  — 29%
Iberian Peninsula 4%  —
European Jewish <1%
Unknown  — 6.24%
Central Asian 4% 3%
Middle Eastern 2%

Here’s what the maps from the two companies look like:

Ancestry's Ethnicity Map

Figure 3: Ancestry’s Ethnicity Map (Outlines = trace DNA amounts)

FTDNA origins

Figure 4: FTDNA’s Ethnicity Map

While the maps look similar in terms of the areas covered (except British Isles, Eastern Europe and Egypt), the ethnicity estimates do not. Why are they so different?

Part of the reason, I’m sure, has to do with the reference panel to which a DNA sample is compared. How the testing company geographically categorizes those references counts a bit, too. Ancestry separates Italy/Greece from the Iberian Peninsula, whereas FTDNA’s My Origins has one group: Southern Europe.

Genetic overlap is also a contributing factor. For instance, those from the British Isles are likely to demonstrate DNA from Scandinavia, Western Europe, and Southern Europe due to the various invasions/population influxes the islands experienced through the centuries. But I would think that at least some of this is accounted for in the process of mapping the various admixtures.

How does that help explain my results? I’m not entirely sure. I only have one ancestor who could be considered to be from Scandinavia (or Germany) going back at least six generations on either my paternal or maternal lines. My one Danish ancestor is  five generations back and would account for only 3.12% of my DNA. So, how do I get 58% of my DNA from Scandinavia? That’s more than half my DNA! Roughly the equivalent amount of DNA contributed to me by one of my parents. I should be able to account for it more recently than five generations back.

The same can be said for Southern Europe. While I can see the possibility of DNA from Southern Europe being present in some of the Swiss/German or Irish ancestors, it’s many generations back. It would likely be diluted with other ethnicities. I can’t really see how it could account for 29% of my DNA—that’s a grandparent!

Nine percent of my DNA from Western/Central Europe seems exceedingly small. Especially when I can count 46 out of 64 ancestors six generations back as most likely being of German or Swiss descent. That’s approximately 72% of my DNA. The difference is almost laughable.

So, I’m a bit at a loss to explain these results.
