@mycortinas,
Can you rearrange your family list you posted above? It was a bit confusing, and you totally lost me when you stated two parents for Maria Garza and Maria Olivares Garza. And then you mentioned Andres' father, but you never said who was Andres? Unless there is another post here that you listed them, please let me know.
