I have a friend named Domingo Jose Quintanilla that says he is a cousin of Selena's. His parents names are Armando and Lisa Quintanilla. He has, I think, five younger brothers also...one of there names...the next oldest...is Mondo. I hope that this helps. I also think that his Aunt or his Grandma is named Susy or Susan. If you have any news concerning this...please e-mail me at email@example.com. Thank you.
