If you have any roots to New Mexico then the New Mexico Prenuptial Investigations (Diligencias Matrimoniales) can be a great resource for you to check out.
These diligencias matrimoniales or pre-nuptial investigations cover the years 1678-1869 and they are of the Archives of the Archdiocese of Santa Fe.
They were extracted and put together in books by Fray Angelico Chavez who also wrote the book "Origins of New Mexico Families, A Study of the Spanish Colonial Period".
These New Mexico Prenuptial Investigations by Fray Angelico Chavez are available in an eleven volume series sorted by last name in alphabetical order.
Even if you do not have a need for them I highly recommend that you download them and put them in your digital library. You just never know when you may need them.
Below is a small thumbnail of the cover of volume one.

I gave two valid credit cards and they were not accepted. I don’t understand.
What were you trying to purchase?
I started the Pre-nutial Investigation and found some relatives already. I have been scouring records looking for birth information on Marcelino Martinez, my grandfather, and his parents. My mother told me his parents were Francisco Antonio Martinez. I suspect they were actually Martin- Serrano. The area is northern New Mexico, specifically Rio Arriba and Taos. I suspect they were from somewhere else.
