I am chatting with a historian of Zacatecas, Mexico and he lives over there. He told me that he recently met someone from San Luis Potosi that has the "padrones" book of Valparaiso, Zacatecas, Mexico year 1648.
He says that Juan De Angon was one of the first settlers of Valparaiso, Zacatecas, Mexico in 1648. That he was "viudo" and had a son name "Esteban Angon" who was the heir of his rancho. Which later became, "Santa Rosa"
In the past I had posted a "pasajero de indias" of Juan De Angon 1606 to Nuevo Galicia:

He is reading that document for me since he is familiar with that style of writing.
Juan De Angon - One of First
He is also telling me that he has the padron of Valparaiso year 1648. There were 60 people, 12 were "espanoles" the rest "indios and castas."
He says that "Angon" is one of the 12 of the "espanoles." I asked him for a copy of the padron of 1648 and he says he will send it to me.
