I knew some of your Los Herreras Escamilla & Loera family members.
Bernabe Escamilla, your paternal grandfather, was the son of Antonio Escamilla & Genara Trevino.These folks were from Cienega de Flores, Nuevo Leon.
Your grandfather Bernabe married Paula Loera whose parents were Romulo Loera & Casiana Salinas...Romulo was the son of Toribio Loera & Nicolasa de la Garza.The Loera people settled in what is now known as Los Herreras in the early 1800's.Casiana Salinas was a member of the Salinas' people who settled near Los Herreras in the very early 1800's...To be specific this Salinas branch settled near San Jose de La Laja which is now part of the Los Herreras municipality.
Bernabe Escamilla & Paula Loera had the following children:
Alejandra, Melchora, Patricio (1911- 2001), Florinda, & Nicolas,Nicolas was Los Herreras Mayor sometime before his death.
I should hope that you visit Los Herreras in the future to see where your ancestors lived in the long past.
Please let me know if I can clarify any area pertaining to these subjects:
