Below are death certificates for several of Gurley and Delila's children. It is interesting that the informants knew so little about their parents as you will note below:
Isaac Gurley Sellers, Jr.: His son, Oscar was the informant but appeared to not know his grandmother's name. He lists Molly as the wife of Isaac. Her name was Mary Holcomb but possibly went by Molly as a nickname.
John Martin Sellers: His informant put John's wife's info in the spaces for his mother's data. He also refers to John's father as Isaac which suggests that Gurley Sr. was Isaac Gurley Sellers, Sr. if you can put stock in this document.
R.J. Sellers: He is the only one that lists Delila Wyatt as the mother.
William Bill Jackson Sellers: His informant didn't know (DK) anything about Bill's parents. And also reports that they were from S.C. which is an obvious error.
