Origen de los Enriquez en Jalostotitlan, Jalisco

Hello to all! Saludos a todos! Hope every one had a great Christmas and also wishing you the best for the new year!

I'm stuck on my research for my Enriquez family in Jalostotitlan. The latest couple I have is Jose Maria Enriquez and Maria Nicolasa Gonzalez de Villasenor. They are my 6GGrandparents. They lived around the mid 1700's. I can't figure out anything before that. Their son, Jose Vicente Yrineo Enriquez Gonzalez (who was a twin by the way) was born around 1785 and married Maria Francisca Romo de Vivar. Vicente's daughter, Maria Gerarda Enriquez, eventually made her way to Amoxochitl (Juchipila area) and married my GGGrandfather Jose Maria Enriquez... yes, there were both Enriquez :-) -- so makes for an interesting line to have 2 last names join in different towns with who knows what backgroud.

Anyway, any help would be great. Does anyone have any info on the origins of the Enriquez in La Nueva Galicia?

Saludos!
