I don't have a Benjamin or Z*** Thomas in my line (that I know of), however, my THOMAS's were located in Chester County Pennsylvania in the early 1800's (1820's / possibly earlier). My ggg-grandmother was born Ann THOMAS in 1811. She had a brother David THOMAS. Ann married Lewis CHRISTY in 1828. David THOMAS died in 1833, and Ann died in 1838. Have either of you come across these names in your search? I have been told by another researcher that there was a Benjamin THOMAS in Chester County Pennsylvania around that time, however, I think he survived to be an adult. Thanks, Mark
