I have to differ with your identification! The lady living with Abram Lord and his wife Melinda, was his mother-in-law, Mrs. Sarah C. (Banks) Weeks Rounsavall. Sarah's first husband, William Weeks, died in Copiah Co., MS in 1834. She married Cyrus Rounsavall in Copiah Co., MS in 1836, with Jonathan Oneal as their bondsman.
Don't know what became of that marriage. By the 1840 census, Sarah Rounsavall was head of her household in Copiah Co., MS, while Cyrus Rounsavall and Jonathan Oneal were enumerated across the Mississippi River from Natchez in Catahoula Parish, LA. Every census year that followed always found Sarah Rounsavall living with her various children's families.
