I am also looking for Aguirres from Coahuila. My great-grandmother, Demetria, was born in San Pedro, Coah, in 1900 or 1901. Her father was a Felipe Aguirre, and she had one known brother, Juan, and two known sisters, Paula and Cedilla. Demetria married Jesus Maria Gonzalez from Monclova around 1916 and came to Texas shortly afterwards. Any possibility of a connection?
