Frances, I wish I could help, but I can't.I have been unable to document my direct line link to Abercrombie's, and have let my research on the family lapse. I do have a documented marriage of a multi-great uncle [Gabriel Jowell/Joel] to Rebecca Abercrombie [b.abt.1784], dau of James.
If you have not already, I suggest you might try to discover what happened to James, s/o James & brother of "my" Rebecca. I believe this James would have been about the right age to have a son go off to TX in time for the Texas Revolution in the 1830s.[Both Gabriel Jowell & his brother John had sons who went to TX at that time.]
I would be very interested if you already have info on this James, s/o James. Mitchell
