Hello, My father is Ernesto Perez, son of Feliciano and Catarina Perez. Catarina's surname was Olivarez and they lived in Santa Rosa, TX. Catarina died in the 50s and Feliciano died in 1982. I'm not too familiar with the Olivarez side of of the family, but quite a few of the Perez clan are still situated in Deep South Texas. My father has two older siblings: Hortencia Perez Prince and Reynaldo Perez. They live in Michigan and Waco, TX respectively.
If this sounds like a connection, please let me know, and I'll find out some more information for you.
