You have been so helpful!Those are absolutely my relatives.Rodolfo did marry again to Gregoria, but I never knew her last name (5/12/06-4/17/78).She is buried in Levelland next to Rodolfo (7/8/03-7/15/74).Rodolfo and Gregoria did have a son named Rodolfo Jr ? (we knew him as Rudy) who has also passed away.The name Hylberto or Gilberto is not familiar to me. I wonder if he died as an infant?
I found a monument for Martina Garza at "Find A Grave," buried at Elim Lutheran Church Cemetery, but was not sure if this was my grandmother. The death date is 8/16/42.
