That's about the way I would interpret the info that I have. I think the reason that I'm having problems with church records is that many records were destroyed during the revolution; That and the fact that nothing comes up in searches for Durango Mendoza's.
I guess I'll probably have to go back to the LDS "Family History Center" and search some more microfiched baptismal records.
I didn't know about Terrazas family. As far as I know, my "Mendoza's" could have been despots too. It would seem that is very likely.
Thank you for the info Javier.
