First, thank you so much for responding.
Origins of New Mexico Families says his name is Alonso "Jola" Romero but his birth name is Alonso Cadimo. He was a criado (special servant) of Felipe Romero and took his name. The document I am looking for is regarding him.
Although I do want to find this record, it is more important to me for someone to show me how to locate records in the AGN. Apparently I've learned enough Spanish to pull information from the church records but not enough to work my way through a modern website.
Thanks again!!
