Moca is capital of the Espaillat province that is located in the Cibao region of Dominican Republic. If your family is known to come from the Cibao, it doesn't hurt to research your lines in a town that had two churches in the 1880s.
I knew that I kept a list for Moca Church Books as I've gone through some of the books for that region of Dominican Republic. I was able to locate the file late last night and decided I would share the list with all to make it easier to navigate through the books in Moca. Moca's two churches are Nuestra Señora del Rosario and Sagrado Corazon de Jesus. I have listed all of the Nuestra Señora books that go from 1821 to 1921. Many have indexes which I've indicated. To explain how to work with the "Image numbers", I provide an explanation on a prior post which you can find here. Hope my list assists you in your research!
Note: Each entry is clickable and leads to the book, if you find a link doesn't work, please feel free to post below and I'll made the edit as soon as possible.
