The death date that you have for him is incorrect, it is his mother's (Mary Ann Clementine Foster). The date is incorrect on Thomas' grave stone. I do not have the exact date, but I know it is closer to 1940, my father, his grandson went to his funeral.
Mollie Frances birth date 21 Oct 1892 (my grandmother)
Stella Mae birth date 21 Apr 1892 (my great aunt)
There is no Minnie or Millie.
