MIguel Rodríguez de Santa Ana y Sebastiana Pérez de Frías

Hi fellow researchers, I've been inactive in genealogy for quite a bit, true it is that I'm almost "retiring" from it, a least to some extent, as I kind of answered the two / three questions I had when I started 15 years ago. Never the less, there are a couple of things that still gives me an "itch", been the main one the unknown (to me) identity of Miguel Rodríguez de Santa Ana, who is my oldest ancestor on a direct father to father line. I only know about some of his kids (all from familysearch.org database).

I wonder if someone has found who he was, specially since he married a 'de Frías' which I know is been extensively researched in this forums. This following part in a post by Mr. Steven Hernandez mentions similar names:

I'm not sure if anything else is known about the groom. These Rgz de Santa Ana are quite tricky due to the constant skipping of their last part of their surname, I know they seems to be very close and related to the Lozano and Quiralte/Quirarte, all of this in Nochistlán and around, but very little I had come across with it.

I'm leaving the topic more as a note to my self than a full question, leaving this door open to any of your comments that in a future may take me in any specific direction. I'm planning on writing down (finally) all I found about my last name and ancestors, and genealogy in general in a little booklet, I have many brick walls here and there, but hopefully will serve as a source to others behind me.

Thank you for any comment or clue you may want to share.
