I believe I emailed you a few month's back regarding your family. I share the same surnames you mentioned in your message. I am interested to know if there is a connection to Juana Vasquez. She and Jose Castro had a son named George who was raised by Frederico Olveda and Claudia Reyes. Claudia was George's older half-sister who raised him as her son. Jose Castro is said to have been an amunition carrier for Pancho Villa. He lived in the same house with Frederico Olveda in 1910. They lived at that time in San Antonio, Texas. They were both born in Mexico.
These could be siblings names from those of your grandparents. The last names and era are too coincidental to dismiss.
