My Grandmother was born in Autlan, her name is Alejandra Topete. LAUREANO TOPETE Y TOPETE and MARÍA WENCESLAO TERRÍQUEZ
She is one of many children born to Laureano and Maria.One of her brothers was named Jose Maria.and Judging from the time line this "could" me your great grandfather.You can see more of my family line further down.Hopefully you can contact someone in your family that may recognize some of these names.
If it is the same Jose Maria/alexandra's brother, then Laureano and Maria would be your great-great grandparents.
Placing your great-grandfather as being born mid to late 1800's.You should be in your 30's or so.
