Phenix Family Genealogy Forum
Hi Larry - yest I think I can help - not with information on children of Preston and Mollie, but on Preston's ancestors.
My great grandmother, Sophronia Lucretia Phenix Thomas had a brother named William Preston Thomas who married Mary "Mollie" Moore July 28, 1881, Hood County, Texas.
Sophronia's parents were Preston Kemper Phenix and Mary Arminda Nix. Contact me at email@example.com for additional information. I do have quite a bit of information on the ancestors.
