Medina Surname

Although I don't have the Medina surname in my tree, I have also been curious about it because the name is common in northwestern Durango. I have various books about northern Mexico in the 1600/1700's, and information about early settlers with that surname has never turned up.With the Inquisition being a powerful institution in Mexico in the 1600-1700's, it seems a name like Medina would have aroused suspicion of a non-Christian background. Maybe a search on the Pares website will turn up some clues.
