I have strong preponderance of evidence for an ancestor and would like
to know if you can suggest any other sources that I  might check out for
PROOF.

I have an ancestor Peter COOPER who went from "probably" Fairfield Co,
SC to Chilton/Autauga Co, AL ca 1820. I have a "very probable" father
for him named Adam Sr. Adam Sr had four sons, according to censuses. One
"disappeared" before or in 1820. The other three were Adam B. Jr.,
Andrew, and George. Adam Sr had three daughters: Mary, Nancy, and
Margaret. Adam Sr's father was named Peter, and he had a brother named
Peter. Doesn't it stand to reason he would name a son Peter? I think
Peter is the one who "disappeared" before or in 1820.

My ancestor Peter COOPER appeared in Chilton/Autauga County, AL before
or in 1820. Among his children were Adam, Andrew, George, Nancy, Mary,
and Margaret. His earliest neighbors in AL were the same men who had
lived near Adam Sr in Fairfield Co ca 1800, so it appears they all moved
together. Their surnames were STRINGFELLOW (Henry), GRAY,
FUNDERBURGH/FUNDERBURK, and POSEY (Francis).

I have probate records for both Adam Sr  and Peter. I have extensive
land deeds for both and census info, and I have checked censuses to see
if any of the brothers or sisters might have moved to Autauga/Chilton,
but I simply can't find a needed PROOF. 

Can anyone suggest documents or other sources that I might have
overlooked?
THANKS SO MUCH FOR YOUR TIME AND HELP!! :)
