I believe that my James Beal was born around 1818, so this information is very interesting to me. Could this James Bell who married in 1818 be my James Beal's father, or could the James Bealle for whom you are looking be my James Beal's father? Unfortunately, I don't have any information on either name. I would definitely be interested in any information you find regarding the James Bealle who escaped the Fort Mims massacre.
Good Luck!
