I put the info into my tree and got several hits. It looks like "young" Benjamin has been in the states in San Antonio since he was 5 with his mother. No mention of his father. He married someone named Paula in 1974 and they were divorced in 1975. One hit in a directory with phone number but about 20 years old or so. Her full name was Paula A Martinez Salas. No leads on that so far and Guadalupe Martinez to generic. In the border crossing it came back Juan Benjamin Diniro Martinez (Diniro not being Mexican I think this is correct person) with mother listed as Guadalupe Martinez de San Miguel. Unknown why that reference. Thank you!
