Ada Mills, daughter of Samuel Mills of VA
I am looking for information that would lead to the maiden name of my ggrandmother, Susan Mills , wife of Samuel of Fairfax Co VA, and later of Washington DC and Baltimore and mother of Elsie Mills Wahl DeDominic, and Ada Mills. I lost track of Ada after the 1920 census. I think my ggrandmother was Susan Simpson, born c. 1867 in VA.
I would also like to discover the maiden name of my great great grandmother, Mary, who was the wife of Joseph Mills .
I would appreciate any help.
