Very exciting news for many BARTLETTs and BERKLEYs - we now have 24/25 matching DNA results:
One from William BERKLEY b 1690 of Westmoreland and Loudoun Co, VA through his son Benjamin BERKLEY
Another from William BERKLEY b 1690 of Westmoreland and Loudoun Co, VA through his son William BARTLETT/BERKLEY
William BARTLETT/BERKLEY d 1804 in Loudoun Co, VA - most of his children went to KY and in the census records from 1810 to 1840 they gradually changed their surname from BARTLETT back to BERKLEY/BERKELEY. One of William's sons, Garner/Gardner, however, went to Berkeley/Frederick Co, VA and then to Botetourt/Montgomery Co, VA (many descendants still in Floyd Co, VA; some to Warren Co, IN) - this line retained the surname BARTLETT.
If there are any BARTLETTs from Garner's line, or any BERKLEY/BERKELEYs from VA roots, you can now verify descent from this line with a matching DNA test.
I have some info on this line, in a Word document, if anyone is interested in receiving a copy.
