My grandfather Manuel A. Caballero was born in 1919 somewhere in Texas (Edna or Elroy we believe). His father (also named Manuel) died when my grandfather was just an infant. This is pretty much all that we know about my grandfather's background. He and my grandmother settled in the Corpus Christi area for a good while and later moved to San Antonio....and most of his grandchildren (including myself) still live in Texas.
Does anyone know about my grandfather's heritage? Also, is the surname "Caballero" Spanish? Or is it derived from Mexico or somewhere else?
