Below is the 1942 Social Security application for Estefana Gamboa, daughter of Andres Gamboa and Francisca Gamboa, wife of Arcadio Arrizola. At the time, she was living in Edinburg. Both of her parents were named in the record.
(No further documentation for this image, which was provided by researcher Erin Rivera. Many thanks!)
I received the SSA Application from Arcadio Jr’s grandson Alfredo ‘Fred’ Jr. He is the son of Arcadio Jr’s son Alfredo B. Arrizola. His email address is Fredjr@wcoil.com. I received the SSA Application from him on 10/15/2012. He said he ordered a copy years before.
