Does anyone have additional/corrected information on the following family?

Abram Boone DeFRANCE (1775-1828) married Mary HOWARD (the Widow SESSIONS?) in 1816, Natchez, Adams Co., MS.
Children:
1. Parke Walton DeFRANCE (1817-1885) married 1st SESSIONS, 2nd MONTGOMERY, 3rd ALEXANDER, 4th McRAVEN and may have had children with each of them.
2. Walter DeFRANCE (1822-1885) married 1844, Claiborne Co., MS, Laura HANKINSON
3. Charles Abram DeFRANCE (1826-?) married 1853 in Louisiana, Sallie HARDEMAN.

I am having trouble finding these families in the censuses. I saw an 1845 Warren Co., MS, court document that stated that the brothers in law of Russell SMITH were E. J. SESSIONS, P. W. DeFRANCE, W. DeFRANCE and Chas A. DeFRANCE.
