We have traced Isaac G. Maxwell b: 1824 in Montgomery, AL d: 03 JUL 1868 in Montgomery, AL   He married Rebecca Helton.  Their son, John Thomas Maxwell, was born 1855, also in Montgomery.  Isaac's father, William A. was born in South Carolina, possibly Pendleton, in 1800.  We are trying to find William's parents.  Any help would be appreciated.
