Hey there. read your post and my family comes from zacatecas, mexico. my mothers last name is Davila, her fathers name is Irineo Davila, her grandfather's name is Refugio Davila, and her Great grandfathers name is Mariano Davila. That pretty much takes us back to the early 1900's. From what i know, refugio and possibly mariano resided in el plateado, zacatecas or (El Plateado de Jaquin Amaro). Please let me know if this helps a little.
