Hi from Dallas. I am Reyes by marriage and Elizondo due to my DAD. His mother was Maria de los Angeles Elizondo Davila from Huinala, Nuevo Leon a suburb of Monterrey. I do know a bit about our ancestry going back to Jerusalem where our ancestors were from.
I was not at the reunion but my DAD was. It went ok according to my Father.
Who was your wife's relative in Monterrey? We have other relative in Texas too. I hope we can keep in touch.
