Luis Lópes Suáres

Is anyone familiar with Luis Lópes Suáres? My family is descended various times from him and his wife Catarina de la Cruz (maybe Hernándes). I just stumbled upon a marriage certificate from 11 February 1673 (in Aguascalientes) that I think was probably a first marriage to Mariana Sepulbeda, because it gives the names of Luis' parents as Juan Lópes and Josefa Xuáres. I am very excited about going back one more generation, but I can find absolutely no mention of anyone in this family before the 1673 marriage.

I do know that Luis died before 1729 - the date of a marriage of a daughter Maria Josefa from the second marriage. I cannot find the marriage to Catarina, but there is a baptismal certificate for sons Bentura (1716) and Simon (1724). There is also a record for a son from the first marriage - Gabriel (1682).

Many of the early records for this family give the surname Xuáres or Juáres, but all of Luis' sons started using Suáres.

Here is the link for the marriage with Mariana - it's the middle record on the right: https://familysearch.org/pal:/MM9.3.1/TH-266-12446-30482-34?cc=1502404&wc=M6QF-2NG:64894501,64894502,107296001
