Araiza y Medina

Hello all,

My name is Michael Araiza and I reside in Tucson, Arizona.
I've been do genealogy for about 6+ years. I have followed my Araiza line from Sonora into Jalisco. Ambrosio Araiza (1746-1819) was the first in my line up north from Jalisco. There has been such wonderful research done and contributed on the Araiza line and I am sincerely thankful to all those researchers. I would love to share anything I know on the surname if any of my info can be of use.

As I have come across, I understand that the Araiza's are in Aguascalientes in the early 1600's, and Fernando Araiza is a Vecino of Zacatecas.

My general question is there any information on the "y Medina" surname?

I have noticed that the "Araiza Y Medina" has been passed down into several generations even when an Araiza is not necessarily married to a Medina. Is this due to importance of the surname?

For example Juan de Araiza y Medina I, his parents were Fernando de Araiza and Maria Guzman, wouldn't the name have been Araiza Y Guzman? Why did the "Y medina" keep carrying on?

Correct me if I'm wrong, but as far as I have read, Fernando Araiza and Juan Araiza Y Medina I are the the first to the new world from Los Reinos de Castilla por un lugar de la vizcaya?

Any info or discussion will be greatly appreciated.

Muchas Gracias,

Michael
