Hi Laura, My name is Catarino Quintanilla Navarro. My Grandfather on my mothers side is also named Catarino Quintanilla. He also died during the 1940's and was put to rest somewhere in a cuidad in Mexico south of Del Rio. I don't have any history on him at all. The name Catarino is a rare name, handed down from generation to generation. not too many men are known to carry the name. I'm wondering ifthere is a connection between our relations.?????
