Hi Sal, Well...this is kind of strange. I live in California and my father's name is Salvador Tapia and his Father was also Salvador as well as my brother and all three of them were born and lived at one time in Guadalajara.. I still have many family members who live in Guadalajara that go by the last names of Ochoa and Lopez. Were you born in 1977? I was born in 76. Interesting...we may have something here.What do you think?
