I'll search for the book to get the exact title, and name of author for you. There were a lot of Quintanillas, and you could very well be related to that same Quntinailla family. Josepha Leal's maternal grandmother, Paula Leal, was married to Gabriel Quintanilla and had 10 children live to be adults. The reason I know this is that one of Paula's children filed an inventory of Paula's assets and claimed one tenth ownership. Paula's house is still standing in General Bravo with her name etched in stone over the doorway; i.e, casa de dona Paulita Leal. I also remember seeing the name Quintanilla over other doorways.
