  1. My name is Elvia Garza Frausto. My great grandfather was Moises Garza, grandfather Federico Garza. Both buried in Matamoros in an old family cemetery called La Teijeritas. I went there in 2003 and could not get the dates off the coffin where they are buried together. The ranch they used to have is also the same as the cemetery. I was wondering if you had ever been there for your research. Lots of relatives with Garza Garza, Villareal etc there.
