Nicanor Pineda research update

You write:
My grandfather was born 1930 in Laredo, Texas where I'm not sure the baptism
records are as in-depth as I've found them to be in Mexico. What's also
interesting is that my grandfather was born when Nicanor Pineda was age 46
and as far as we know, my grandfather was his first child.

If your grandfather was baptized in a catholic church, the records are
definitely as detailed as those in Mexico. The listing of great-grandparents
was a requirement under some sort of council and was mandated by the Vatican
beginning in 1810 or so.

Do you know what parrish in Laredo your grandfather was baptized in?
