Hildred, thank you for your prompt and informative reply. Quite a few surprises. I did not know that (any Treakle) Elizabeth Treakle married into the Yerby family in 1776. I have two Yerby marriage records:
Elizabeth Yerby & William Treakle, May 15, 1837, Lancaster Co., Va
Mary Ann Yerby & James Treakle, April 20, 1846, same place.
That is as far as I go at the moment. Thanks again.
