I don't know if this helps BUT ...
My great grandfathers name was Jose Jauregui born about/maybe in 1898 in Teocaltiche, Jalisco, Mexico.
He had 5 children with Juilana Islas named:
Irene Jauregui
Salvador Jauregui
Teodulo Jauregui
Maria Guadalupe Jauregui
Urbana Jauregui
We were told Salvador crossed into the states with his father Jose Jauregui into Arizona.
