Preliminary Comparison of Cheshire Stubbs and Glouc-Worc Stubbs DNA tests
Hello to all,
I realize that, so far, there are a very limited number of DNA submissions in the Stubbs DNA Project. However, we have already established that expressing opinions is a Stubbs trait, so I feel it is my genetic right to dive in..
If we do a comparison of Stubbs data available on "The Stubbs DNA Project"(1) with Stubbs data from the Sorenson Molecular Genealogy Foundation(2) we see there is some overlapping in the data.
Two of the subjects from the Stubbs DNA project, and two from the Sorenson study descend from three sons of John Stubbs(1732-1803) and Esther Maddock.
From the Stubbs DNA Project:
S-2 descends from William Stubbs(1784-1857) son of John and Esther
S-3 descends from Thomas Stubbs(1775-1844) son of John and Esther
From the Sorenson Molecular Genealogy Foundation we have two descendants of Robert Stubbs and Delilah Parham. Robert Stubbs(1819-1893) is the son of Joseph Stubbs(1772-1862), who is also a son of John Stubbs and Esther Maddock.
At the 12 markers common to the Stubbs DNA project and the SMGF, the number of repeats at each location is identical for descendants of the two brothers, Thomas and Joseph Stubbs.
Descendants of the third brother, William, differ by one repeat at location DYS390 and one repeat at the more rapidly mutating DYS385a. It would seem likely, therefore, that their father John(1732-1803) and his father Thomas(1692-1763) had the same pattern as the two brothers Thomas and Joseph(grandsons of Thomas of Worc). My descent is through Thomas, Jr(1736-1769), the brother of John(1732-1803). My DNA was submitted recently, so I look forward to either confirming this hypothesis or perhaps, being made a fool. Remember, we Stubbs have opinions, but it is not part of our birth right for them to be necessarily accurate.
Assuming the presumed genealogy for William Stubbs(1784-1857) is correct, it would seem that there have been two mutations, by a single repeat each, at two locations, since William. Do any of you guys live near a nuclear power plant?
Cheshire Stubbs
SMGF also has data from a descendant of Stubbs in Cheshire going back to Matthew STUBBS
b1731, Davenham, Cheshire, England
If John Stubbs(1732-1803), son of Thomas, b 1692 in Worcestershire, is representative of Worcestershire Stubbs, then Cheshire Stubbs and Worc. Stubbs differ by no more than two repeats among the 12 markers. Worc Stubbs has 14 repeats at DYS393; Cheshire Stubbs has 13 repeats. Similarly, Worc Stubbs has 11 repeats at DYS391 while Cheshire has 10 repeats It is possible that additional data from other representatives of each county may show a closer relationship.
Hopefully, as additional DNA data becomes available, the mutation "clock" may be calibrated to assess the number of generations required for a likely mutation.
Looking at S-1, the other submission to the "Stubbs DNA Project", it is interesting to note that at the two locations where Cheshire and Worc. Stubbs differ, i.e. at DYS393 and 391, S-1 has the same values as Cheshire Stubbs.
Well, I've climbed quite a ways out on a limb with a limited amount of data, so I will shut up for now.
This is an exciting project. I look forward to seeing more DNA data from our kin in the U.S, the U.K., and elsewhere.
I also look forward to heaing other Stubbs opinions, even from those of you who wish to saw off my limb.
