John: I have a little info on the Campa family I am researching although I don't have an Antonio. There are several different Campa families in San Antonio. Some names in the family I am researching are Eduardo, Edward, Adolph, Amalia, Emil, Sydney, Grace, Patrick, Susan, and Gertrude.
Eduardo was married to a Sadie Irving. If any of these names are familiar to you. We may be talking about the same line. Let me know. I can be reached at edrudder@hotmail.com
