Searching for information on Antonio Pantaleon or Don Antonio Gil Gutierrez

Hi everyone.

Looking for help in finding records on:
(1) Antonio Pantaleon &
(2) Don Antonio Gil Gutierrez (Antonio's owner and possible father).

I believe my ancestor that "started" the Gutierrez family is: Antonio Pantaleon, a slave of Don Antonio Gil Gutierrez and son of Maria Antonia (last name is not mentioned), also a slave. Antonio Panteleon's father is listed as "unknown."
(Fascinating)!

In this recorded:

Antonio Pantaleon is mentioned as marrying Anna Maria Placenia, daughter of Jossefa Ruiz and her father's name I can't make out on February 26, 1772

I believe Antonio Pantaleon changes his last name to Gutierrez because other records show his children with the Gutierrez surname. In this following recorded, their son Jose Maria Norato Gutierres Placiencia, christened 17 Feb 1787 at SAN MIGUEL EL ALTO,JALISCO,MEXICO reflects that change as follows:
