Robert: You and I may be related. I am descended from the union of Isabella Abercrombie (sister of Mary Caroline Abercrombie) and Josiah R. Blackwell.
My info.re. Mary Caroline is that she was born about 1740 and that she was married two times: (1) to Benjamine William(s) and (2) to William Scott O'Daniel.My info. also states (no proof) that she and her 2nd husband lived in Pickens Co.,Alabama. I hope this helps you!
I have a question for you--I show that the 1st wife of James Abercrombie was Elizabeth Sherrell who was the mother of both (1)Mary Caroline and (2) Isabella. Do you know if this is correct? If so do you have any proof?
Hope to hear from you -- I have e good bit of Abercrombie info.--will be happy to share!
