Thank you for your reply. Well I am not sure where to begin because my grandparents separated many years ago and my grandmother moved to Guadalajara with the kids and many of them moved to Zacatecas or the U.S. My great grandparents are Cristino Alcala and Ambrosio Alcala. My grandfather still lives in Tepatitlan. He has remarried and has started another family. His name is Loreto and one of his brother's name was Jesus Alcala and he had a sister named Cecilia Alcala. Let me know if this helps.
