Hi Yes, I think the 1830 appears to be the only answer. To check for a weird spelling of Barrier.Right now Hannah appears the only one of record in 1830 in Jackson Co, AL and she is living alone.The only other thing would be if Abraham was a witness on a deed or other instrument which would support his move to AL.
Abraham dying at age 90 is possible I guess, but rather unusual back in that day.
Speaking of unusual....we have a supposedly German speaking Abraham who marries Reynolds (English) and his daughter marries a Massey (English) which again is possible but just saying he is a Tory and that explains it... is in my opinion a little shakey.
There were Barrier's settling early in VA....Augusta Co, VA (See Chalkley papers (court records) on www.usgenweb for Augusta County, VA ....or use usgenweb search engine for VA and Barrier & Berrier...as early as 1740ish) I have never searched for Massey's or Reynolds in the Chalkley papers but those families might be there too. Good luck!! Stephanie
