Can Someone Tell Me Where The Family Name Of Elizarraraz Come From?

For me I am just trying to learn about my dad's side of the family. I
know that my Dad is Spanish and Basque. I don't know which year it was
that my fathers great great grandfathers came to Mexico.

All I know is
the history of my Dad's family from the stories that were passed on.
There were two big gated ranches one belonged to the Vazquez and the
other to Elizarraraz. The two family married one another.

My father is
that product.

From this story I discovered that I was part Basque. I
always wondered why my father's great great grandparents came to Mexico.
Spain and the Basque country are so beautiful. The ranches that I have
not yet gone to visit are in Guanajuato Mexico.

My father told me about
an underground room that was made under the ranch. I wonder if it still
there and if it would tell me more about my family. Maybe names of
cousins or letters. Loved ones. The ranch has changed what was there
hardly remains. Many family heirlooms and treasures stolen from a g
roup that my grandmother called Los Crinacos (A type of pancho villa
group from what my dad says)...They were thieves and would still women.

The Basque and Spanish men would fight them off. My grandmother tells me
that she would go into hiding and sometimes on top of a roof and some
would hide in this hidden underground room.

Inshallah I will visit
Guanajuato soon and see if I could find clues or see what remains to
maybe one day track records of both my Spanish and Basque families.
