My Alexander line ‘daughtered out’ so long ago that I have no living male descendants to participate in the yDNA surname study. Mary Alexander (1814 KY – 1904 MO) was the daughter of Reuben Alexander and his wife, Jane/Jean Allen Wilson. She had many siblings but only these brothers that I know of that lived to have sons of their own:
(1) Edwin Alexander b. 1803; m. Cynthia Herrin; d. before 1850 in Indiana. They had sons: George, John A., Edwin G. and James H. (2) Reuben/Ruben Alexander b. 1818 KY; m2 Keziah Criswell; d. 1885 in Fremont County, Iowa. They had sons: Edwin and John Charles. (3) Eli Harris Alexander b. 1822 Indiana; m. Sarah (aka Sally) Flinn; d. 1903 in Decatur County, Iowa. They had sons: Curtis L., Eugene O., Morris and Edward H.
I have identified the parents and the grandfather of Reuben Alexander but it would be immensely helpful to know how (or if) this Alexander family is genetically related to any of the others in the Pennsylvania/Maryland/Delaware region before the Rev War.
Y-DNA which follows the paternal line (is passed nearly unchanged from father to son for many generations) is very useful for genealogists and not useful at all for anyone else! So if there is anyone out there related to this line and if you would be interested in participating, I will be happy to pay for the test!
