My biological fathers last name is Guajardo, I know he is of Spanish descent but I don't know much about where my family comes from. My fathers name is Mario Guajardo, his siblings are Sanjuanita Guajardo, Milly Guajardo, Manuel Guajardo, Mellissa Guajardo and a young brother who passed Jorge Guajardo. I know some of my relatives are near Houston Tx and others in SoCali... But I just want to know if they derive from Mexico or Spain.. I'm 24 and don't know that side of my life and am very eager to learn more.
