More exciting DNA news

Found a match for McGuire DNA on the 11th chromosome.

I think.

I am still taking baby steps when it comes to genetic genealogy. I think, "Yay!" I've found a match for this brick wall or that brick wall," only to discover that it's a match by coincidence. Or my fragrant cousin who really understands gg cautions me, "It might be a match."

You still have to prove it using DNA triangulation or historic documents.

Well, here's one I can prove with both.

Three of the relatives in my line match one relative in another line of descent from Timothy McGuire and Mary Finney. Timothy was born about 1740 and died about 1790 in Greene County, GA. Mary Finney was born about 1740, died about 1796 also in Greene County, GA. These two are the most recent common ancestors for all three in my line and the one in other cousin's line.

I ran the DNA data for all four people through Gedmatch.com and got exact (gg-speaking) matches on the 11th chromosome. Four people--there's the triangulation, though it will be stronger when we can get another line to share test results.

My line is descended from Davidson McGuire and Margaret Kelley. Cousin's line is descended from an additional Timothy McGuire (so many Timothys...). All of this can be proved using historic documents from AL, GA, and PA.

SO...THUS...HENCE...my assertion that McGuire DNA has been found!

HURRAY!!!

Unless, of course, it's Finney DNA.

The search continues.
