I am interested in your post because Martha F. (Mattie) Allen is my gg-aunt. Her parents are Hogan Allen and Frances Eleanor Rushing. I don't have Andrew's death date.
I have only one child, Sarah Ellen (Sallie), who married George Keener. You say you have a few blanks on the children. Obviously, you have more than I have. Any information you can share would be appreciated.
I have a lot of information on Mattie's parents' lines if you are interested.
