The early population of New Mexico was generally both Spanish-speaking and Catholic. As such, the sacramental records of the towns and villages present an important avenue of research and may provide the names of several generations within one document. Catholic sacramental records (baptisms, marriages, and burials) are rich in vital record information and may prove a valuable alternative in cases where vital records are not available. The New Mexico Genealogical Society has published an online article titled, Locating Catholic Church Records in New Mexico, Rio Arriba County. This index of church records includes the parish, the location of the church, the missions included and microfilm dates and reference numbers in chart format. Some of the films are available in the Family History Library, and those that aren’t at the library have reel numbers found in the Santa Fe archives.
