Decided to start a new thread on this: 

in an earlier post, Daniel Méndez Camino said: 

"Sebastián Pérez de Ornelas, my tenth great-grandfather, married Leonor González de Ruvalcaba, daughter of Juan González de Ruvalcaba and Leonor Franco de Paredes. I don't know if this Ornelas is related to the same family that settled in Los Altos, but I've only seen a few people with the surname Pérez de Ornelas; I don't know its origin."

My ancestor, Juan Pérez, AKA Juan de Santoyo, born about (or before) 1624 (probably in Lagos), had a probable relative named Gerónima de Ornelas. 

Listed in Juan's household in the 1669 Padron de Santa María de los Lagos is Gerónima de Ornelas, Viuda, living with Juan's widow, Antonia de Villegas, AKA Antonia de Mendoza, and their children (all of Juan and Antonia's known and suspected children assumed surnames of Santoyo, Pérez, Villegas and/or Mendoza).

I have no idea how Gerónima de Ornelas is related to Juan Pérez (AKA Juan de Santoyo). Sister? Mother? Daughter? Daughter-in-law?

The order in which she is listed in the household infers she is not a servant but a relative. 

But i cannot help but think there may be a connection between my ancestor Juan Pérez (AKA Juan de Santoyo) and Sebastián Pérez de Ornelas (who is also my ancestor thru his daughter Inés).

At least 2 of Juan's grandchildren were named Sebastián.

I read another post earlier this week that stated an unknown daughter of María Rubio and Diego Pérez (died late 1620's) had a son named "Juan Pérez." Could this son be the same person as my ancestor, Juan Pérez (AKA Juan de Santoyo), who was probably born mid 1620s (about 1624)?

Any thoughts, advice or theories are welcome. 

Thank you. 

Best regards,
