Samuel Rankin (abt. 1734 – abt. 1816) m. Eleanor Alexander: YDNA Evidence

In August and September 2016, I posted a two-part article about the possible family of origin of Samuel Rankin (nicknamed “Old One-Eyed Sam”) of Rowan, Mecklenburg and Lincoln counties, North Carolina. His wife was Eleanor (“Ellen”) Alexander. I just reread the posts. They were tedious, prolix, and packed with trivial information of no possible interest. I apparently have an unattractive propensity to beat dead horses. Moreover, Y-DNA information on the issue has come to light which moots most of one post.

Here is their replacement. It just cuts to the chase re: discredited theories about One One-Eyed Sam’s possible parents.

Rankin researchers have had two main theories about the identity of Old One-Eyed Sam’s parents:

Theory #1 – Joseph and Rebecca Rankin of White Clay Creek Hundred, New Castle County, Delaware (1704-1764) . Two of their sons who belonged to the same generation as Old One-Eyed Sam moved to Guilford County, NC. The primary source for this theory is Rev. S. M. Rankin’s 1931 book, The Rankin and Wharton Families and Their Genealogy.[1]

Theory #2 – Robert and Rebecca Rankin of Guilford County, North Carolina ( “R&R”). Before migrating to North Carolina in the mid-1750s, Robert appeared on the 1753 tax list for West Nottingham Township, Chester County, PA.

Y-DNA testing conclusively proves that both theories are dead wrong.

Here’s a bit about the DNA evidence.

The Y-DNA evidence re: Theory #1

There is a Rankin DNA Project which provides (anonymously)  members’ Y-DNA results online.[2] One member – call him Joe – has a solid paper genealogical trail proving he is descended from Joseph of Delaware. I located another proved descendant of Joseph of Delaware via conventional paper research – let’s call him “Mr. X.” Joe convinced Mr. X to Y-DNA test. Mr. X and Joe are 37-marker matches with one mismatching marker. Genetic genealogists call that a “37-marker match with a genetic distance of one” (or “GD=1”).” That is a darn good match. Furthermore, the two men descend from different sons of Joseph of Delaware so their close match isn’t a function of having a recent common ancestor, such as a great-grandparent. Joseph of Delaware is their common Rankin ancestor.

With two closely matching Y-DNA samples and two solid paper trails, there is a high degree of confidence that Joe and Mr. X provide a good picture of the Y-DNA of descendants of Joseph of Delaware – as well as those who aren’t his descendants.

The Rankin DNA project has four members[3] whose paper trails prove them to be descendants of Old One-Eyed Sam and Eleanor Alexander Rankin. None are a match – not even remotely close – to Joe. Y-DNA evidence thus proves conclusively that Old One-Eyed Sam cannot be a son of Joseph of Delaware.

The Y-DNA Evidence re: Theory #2

 The Rankin DNA Project has four participants whose genealogical paper trail shows they are descended from R&R, Robert and Rebecca Rankin of Guilford. None of them are a Y-DNA match with descendants of Old One-Eyed Sam. Again, the Y-DNA results are not even close. Old One-Eyed Sam therefore cannot be a son of Robert and Rebecca of Guilford, either.

Case closed. We must apparently find a matching Rankin on the other side of the Atlantic to learn more about Sam Sr.’s family of origin.

  1. I would be so grateful for some guidance especially about the DNA tests. I have looked at sites and articles re: the Rankin clan but can not get a handle on my grandfather Charles C. Rankin and his father Andrew Rankin. I gather from family stories that the family came to Ireland during the persecution of Protestants and then to the United States. Charles Jr. and his son Charles III are living in North Carolina where surely they shold be able to find links somehow. Thanks for any interest in their geneology. gloria rankin potter

    1. Gloria, I apologize for being so slow to respond to your comment!

      Do you have a living male relative named Rankin? If so, get him to take a Y-DNA test! Go to the website at FTDNA and select Y-DNA and start with a 37-marker test. (By the way, I am not affiliated with FTDNA and don’t make anything by suggesting them). Whoever tests should join the Rankin DNA project so that his results will automatically be uploaded to the project.

      Since you know the identity of your great-grandfather, I’m betting you an find a first or second cousin to test. If not, I will be GLAD to help you! Where in North Carolina have you found Andrew Rankin living? Contact me via email if you want to talk more.


  2. Hi, I would like to learn more about the Rankin DNA Test research. Samuel and Eleanor Rankin are my 9th generation ancestor. I would like to understand how to read all the numbers and know what they mean. Thank You, Alan Jolly Hartgrove
