Upon a quick search of the information that I have here at home:
WB Wall married Sarah McCall 1-26-1887 in Johnston County. His parents were listed at MT Wall and LJ Wall but her parents were not listed.
Marby T Wall married Louisa J Talton 4-22-1855 in Johnston County.
WB Wall & Sarah Wall are buried in the Talton - Wall Cemetery (which is near where I live) According to Cemetery records:
WB Wall b. 4-29-1866 d. 1-24-1915
Sarah M Wall b. 1-21-1865 d. 2-19-1946
Sarah has a death certificate in Johnston County which list her parents, but I think the informant was wrong when listing the last name. They have it as McWall and it is suppose to be McCall. I have attached her Death Certificate.
