Hello Cristina, my name is Selma. My maiden last name was Echeverria and I come from a long chain of Echeverria's. Is there any other information you may have on your father? DOB, birth place, relatives etc. Hope I can help. I too am searching for my biological father so I know how important any piece of information may be. I have several relatives here in California with the same last name, but none with Hernon. Let me kow of any other inforamtion you may have and hopefully I can help you find some sort of connection.
