All the names you mentioned are distantly related to my mother. Her name is Estefana Alvarado Abrego Aguirre. It is my greatgrandmother Monica Aguirre that is the link. I'm not to good at dates but I know I recently heard your relatives mentioned by my parents when talking to my great uncle. My parents and ancestors including Monica were from Mecuaniate now known as Congregacion Hidalgo, Los Ramones N.L. Mex. As I go back in my ancestry I do find that names were repeated in families quite often. If you find that the name Monica Aguirre comes up in your search, Please contact me via e-mail.
