It could be that the same priest in Jemez was not using surnames either. Ran across these two burials, one of which I needed to fill in some gaps in my database of Gallegos.
On July 29, 1735, buried Juan Manuel (no surname), español, about 40 years of age, and was married to Catharina Gutierrez. (214)
On May 13, 1740, buried Nicolas Gallego, español, about 40 years of age, married to Sabel Xaramillo. (219) This couple was married in 1734 at Albuquerque and I have one child for them after he is buried; Josefa who married Domingo Griego. I used her age from the diligencia, could she have been off five years in citing her age?
