I did find the marriage of A J Allen marriage to Madeline Peice July 27, 1865. I found J A Allen 25 of Gordon with M E Allen 20 years in Gordon 1860 census Claiborne ward 2. I found Allen M A sis in law born Mar 1837 listed as widow living with Dowson A H miller in Homer. There are listed as a family with his wife and children on the 1900 census in Claiborne ward 7. Hope this is helpful to you.
