Happy to help! I've spent quite a bit of time on this family unit but still do not have a clear idea of who Virginia Rebecca's parents were.
Virginia Rebecca's daughter was Ether Elizabeth "Mattie" ROBERTSON, who married a man 28 years older, a Mr. Pinkard Jefferson STANLEY Jr. They had at least six children: one of whom is buried next to Virginia Rebecca--little Ada Marie STANLEY. I suspect the 1900 census taker mispelled the family nickname of Mattie as Nettie? Mattie is referenced as "Mrs. Mattie" in her sister, Olive's obituary, but "Mrs. Ether E." in her own death certificate.
I am not sure why Alfred is not listed on the Texas death index other than deaths were not tracked officially (meaning death certificates were not always created/recorded/filed) in many states until as late as the 1950s. In the 1910 census, Virginia R was listed as the mother of 4 children with only 2 living. Since her daughters, Ollie & Mattie lived past adulthood, then Alfred must have died before 1910. We know Theodore died in 1893 because of the bible entry.
I will have to spend some time of William ATWELL & Eliza ASKEW--this is the first time I've heard of this couple.
