Hello Lynda,

Here is a description of New Mexico roots ltd “New Mexico roots ltd : a demographic perspective from genealogical, historical and geographic data found in the diligencias matrimoniales or pre-nuptial investigations (1678-1869) of the Archives of the Archdiocese of Santa Fe: multiple data extracted and here edited in a uniform presentation by years and family surnames.”

From the above, it seems that they may be in Santa Fe. It might be well worth inquiring with the church.

FYI: The following link contains 11 books on Diligencias Matrimoniales for New Mexico http://digitalrepository.unm.edu/cswr_reference/5/
