I agree with Art. Since you have him married to Parthena (Tutor) Waldrop then his parents are Robert Anderson Jr. and Maria Thomas who are both already on Wikitree. And he did not have just two children he had several children.Let me know if you need more help.
Going to follow up on this information. I think maybe HEnry had been married before Arthany? We have not been able to find marriage record for them yet. Thanks for the help. I know on Ancestry PArthenia/Arthany is listed as also being an Anderson. The marriage record for her was found in Pontotoc County, MS and John Waldrop maarried Mrs A Anderson. To me Mrs. means she had been married. Her daughter California Waldrop said she was a Tutor. I got her death certificate and my grand father gave the information on the death certificate, and it has don't know for both her parents name. What a kicker.
