I had a great grandfather by the name of Theodore Moya who lived in Falfurrias, Texas up until his death in December of 1988. My gradfather Corrando came to Chicago, Illinois from Corpus Christi, Texas in the 1950's and had 3 children, one of which was my mother.
It was very weird how my mom found my grandfather's side of the family. She went through every Moya in the Chicago phonebook until she found a cousin who put her in touch with those in Corpus Christi. We discovered my mom had 3 older brothers and we actually met them before thanksgiving 1988. It was pretty cool. We still keep in contact to this day.
Good Luck in finding the answers you are looking for.
