James Farquhar: How Are We Related? Only DNA Knows

This entry is part of the 52 Ancestors in 52 Weeks series.  This week’s prompt is DNA.  To see other posts in this series, view my 52 Ancestors in 2019 index


Analyzing my father’s DNA has given me many insights into our family. It’s helped me sort out pedigree collapse and formulate theories about the brick walls on these lines. I wrote a four-part series about my paternal DNA super clusters earlier this year, and during that analysis one small cluster stood out among the interrelated mess:


Paternal Cluster 21 among “Super Clusters” A-D, as interpreted from results of Genetic Affairs Auto-Cluster Tool, run date of 3 Jan 2019

UFO conspiracy theorists have Area 51; I have Cluster 21.

My study of Cluster 21 has led me to James Farquhar — an ancestor completely unknown to me and one I’m still not sure how we’re related.

Cluster 21, as defined by Genetic Affairs’s auto-cluster output, contains nine matches to my father. I was able to access or construct trees for five of these matches, and all led back to James Farquhar and his wife Sarah Lockhart:¹

(Only Generations 1 – 4 are shown for testers’ privacy.)

So, who was this James Farquhar?

James Farquhar was born before 1755² , possibly in North Carolina.

James was a veteran of the American Revolution. From the fall of 1775 through April 1776, James served as a captain in the Hillsborough District Minutemen, seeing action at the Battle of Moore’s Creek Bridge.³ After this group was disbanded, James joined the Northern Orange County Militia, again as a captain.⁴ The regiment split in April 1777, and James became part of the Caswell County Militia where he served as captain until the end of the war.⁵ The Caswell County Militia saw action at many battles, including the significant Battle of King’s Mountain and Battle of Cowpens.⁶

According to state and federal census records, James lived in present-day Person County from 1777 through 1800.⁷ He appears in several deed book entries in the Bushy Fork community throughout the late 1700s.⁸ He likely died in early 1814, as court proceedings began on 7 Mar 1814 in Person County to settle his estate.⁹


But, more importantly, who is James Farquhar to me?

One — and maybe the only — perk of having pedigree collapse is the ability to rule out large chunks of family when someone doesn’t match those lines. I have this situation with my Farquhar matches in Cluster 21. In fact, my father only has one close match to these mystery Farquhars: his second cousin J.W.

Both my father and J.W. are great-grandsons of John McMurry and Mary Smart. Unlike my father who has Smarts on both sides of his family, J.W.’s only Smart relation is Mary; it’s made J.W. a valuable “control match.” J.W.’s test results are also helpful in identifying our Farquhar connection. Because none of my father’s numerous other Smart testers match the Farquhars — but J.W. does — I strongly suspect our Farquhar connection is through John McMurry.

Unfortunately, I don’t know much about John McMurry. He was likely born in Mississippi in the mid-1850s.¹⁰ He somehow made it to Jackson Parish and Winn Parish, Louisiana, by 1880 – 1900.¹¹ Because I know so little about John McMurry, let’s trace the Farquhars instead.

Remember the Farquhar tree above? It has an important clue: all the matches descend from John Farquhar. Four matches are descendants of only John Farquhar; the fifth match descends from the intermarriage of John and his brother James’s family (the reason why that tester matches my father at 93 cM, a slightly higher amount than the others). My Farquhar connection is somewhere between John Farquhar, who was born between 1785 and 1794,¹² and John McMurry, born in the 1850s.

No definitive formula exists for estimating how many generations exist between two dates. There’s always outliers like a 15 year-old mother, or a man who fathers a child well into his 70s. However, I’ve used two estimates to examine how many generational links could exist between John Farquhar and John McMurry:

Hypothetical Two-Generation Estimate
(20 years between generations)

My own conservative estimate is 20 years minimum between generations. Applied to this situation, it equals two unknown ancestors between John Farquhar and John McMurry. In this scenario, John McMurry is the great-grandson of John Farquhar. Because the birthdate for John Farquhar is known only as the range of 1785 – 1794 on the 1810 census, I used the midpoint (1789) and calculated forward 20 years from that date. The final jump then results in 26 years between John McMurry and his parent, also using 1855 as a midpoint for John McMurry’s unknown birthdate. I feel this two-generation scenario is the maximum number generations between the two individuals. Increasing to three generations would be an average age of 16.5 at the birth of each descendant. It’s possible, but not very likely for several successive generations.


Hypothetical One-Generation Estimate
(33 years between generations)

Another possibility is the “law of three generations.” This rule-of-thumb estimates three generations make up each century.¹³ On average, males are slightly older than females when they reproduce for the first time, so using this estimate accounts for at least two of the three individuals in my scenario being males. Adding 33 years from John Farquhar’s 1789 midpoint birth year results in only one generation between he and John McMurry.

I feel either of these generation estimates could be accurate. For certain there is at least one ancestor between the two Johns. John Farquhar died before 1833¹⁴ — well before John McMurry was born.

Another tool I used for my analysis is the What Are The Odds? (WATO) tool at DNAPainter. WATO allows users to construct a tree, specify how much shared DNA a descendant shares with the target (in this case, my father), and then set hypotheses. WATO eliminates hypotheses that are mathematically impossible based on the shared amount of DNA and also ranks hypotheses based on their likelihood.

My Farquhar WATO tree was the largest one I’ve ever created. I covered every possible scenario — including half-siblings — for the first four generations of Farquhars, beginning with James. The result was a WATO tree that barely fit on my screen at maximum zoom!

Farquhar Match “What Are The Odds?” Tree, compiled 8 Apr 2019, DNAPainter.com

When complete, WATO gave me eight hypotheses with a score greater than “1” of how John Farquhar and John McMurry could be related:

Likelihood Score = 12
John McMurry is the son of Wright Farquhar and Phoebe Rimmer.

Likelihood Score = 11
One of John McMurry’s parents is the child of Wright Farquhar and Unknown.

Likelihood Score = 10
John McMurry is the son of Stephen Farquhar and Unknown.

Likelihood Score = 8
John McMurry is the son of Stephen Farquhar and Rachel Raney.

Likelihood Score = 5
One of John McMurry’s parents is the child of John Farquhar and Nancy Nichols.

Likelihood Score = 3
John McMurry is the son of Alfred Farquhar and Unknown.

Likelihood Score = 2
One of John McMurry’s parents was the child of Wright Farquhar and Phoebe Rimmer.
OR
One of John McMurry’s parents was the child of Alfred Farquhar & Unknown.


And that’s where my current understanding of my Farquhar family ends. My next step is to search for records about these possible connections, hopefully finding some record connecting a Farquhar with a McMurry. I also see much value in testing the Y-DNA of a male descendant of John McMurry. It could tell me if the Farquhar connection is maternal or paternal for John.

Cluster 21 is no longer my conspiracy theory. James Farquhar, you are out there.

  1. Hello, distant relative! This is brilliant. I’m also descended from James and his son, John, but through the Alfred/Texas connection after John and his wife, Nancy, died of cholera in MS and AL en route to Texas in the early 1800’s. After Captain James died, the sons sold everything and took a caravan of families south. Some names in that caravan included Wright, Hargis, Berry, and Moore.

    Alfred became the ward of James, Jr. and was later married several times. He had other children, including my ancestors, who are missing from your tree. At least one of his children had a large family, with over 10 of them living well into adulthood.

    A bit of fun about James, Jr.: James owned a large ranch in central Texas and hosted the German Prince of Braunfels there in the 1800s, when the Prince was touring Texas to find land for a German colony. Many Germans eventually settled central Texas, and the town of New Braunfels was named for the Prince. In addition, James gave land to what would eventually become the first location of Baylor University.

    Do you have a Texas connection? That could help you solve the mystery.

    1. Hi, Nancy — thanks for reading! I’ve done more research since I originally wrote this post. I believe the Farquhar/McMurry connection may be in Hinds County, Mississippi. Still a work in progress. Have you done a DNA test? Would love to compare results!

      1. I have and it’s in Ancestry, but I haven’t published my tree publicly. It would be great to see the results.

        I’ve been working on my tree for years, and have never found James’ origins. My hunch is that he was a second son who immigrated due to inheritance laws in Scotland, but I’m not sure. Have you found anything else?

        Cheers,
        Nancy

        1. Please send me your username on Ancestry privately via email; I’d love to check our data.

          I haven’t done much research into James Farquhar. I’ve been mostly focused on figuring out my McMurry connection to the Farquhars. But once I make that connection, I will definitely be exploring him more!

          1. I just saw something and wasn’t sure if you found it, too. Susanah Farquhar was the daughter of Elizabeth Moore and William Farquhar. She married Richard McMurray Whitfield, who was born around 1800 and died in Texas. His mother was McMurray. !!!

  2. Correction- some records list him as Minchew, but the North Carolina wedding registry shows his name as Richard McMurray Whitfield and the witness was Richard Minchew.
