Hello: I'm having trouble locating my relatives in Mexico. My dad is Ernesto Joseph Luna. His father was (is, not sure if he is deceased) Jesus Luna. Jesus was an agricultural inspector in Guadalajara which is where my father was born. He was married, had an affair with my grandmother, and my father is a result. My grandmother immigrated to the U.S. about 1946. I'm told that my paternal grandfather was from Monterrey. My father was born in 1942. I know I have many relatives in Mexico still, in Guadalajara and in Mexico City. One if my dad's cousins was a neurosurgeon in Guadalajara. Her name is (was - she may now be deceased) Mercedes.
