I believe she is the daughter of Henry Mason Poss (22 May 1844 to 21 July 1921) and his wife Lucy Ann. The family is in the 1870 Crenshaw Co. AL census on p. 95b and the 1880 Washington Co. TX census on p. 72b. Henry's father Elijah Smith Poss (abt. 1823 to 1897) is on p. 98a. The family came from Wilkes Co. GA. Henry's other children are Dosi Alice (b abt 1867 AL), Wiley (b. 1870 AL), Callie (b. abt 1872 AL), Jemima (b. abt 1877 TX), and Lizzie (b. abt 1879 TX). Henry was the brother of Sallie Poss, who married Walter R. Coe. I don't have any further information specifically on Ida. Good luck with your research (and please let me know if you ever discover who the elusive parents of Elijah Smith Poss were).
