I don't know if this will help Denise, but I, too, have roots in Nadadores
that were Tlaxcaltecos, and they were identified as such in their
children's birth certificates (Lucas and Tomas), the latter having been born in
Gigedo, Coahuila (now known as Villa Union).
Gaspar Bermeo married abt 1742 MaCandalaria de los Rios in Nadadores,
Coahuila (Indios Tlaxcaltecos)
acquiring a new language/Nadadores
Thanks so much for the information!
This is what I have in my genealogy :
MANUEL ROMO was born (date and place unknown). He married MARIA YGNACIA RODRIGUEZ 21 Feb. 1816 in Nadadores, Coah., daughter of Juan Rodriguez and Maria Thomasa Valdes. She was born (date unknown) in and died (date and place unknown).
Their son (Don) Thomas married Maria Luciana Espinosa, and her grandparents' surnames are: (paternal) Espinosa, Araujo, and (maternal)de la Garza and Tijerina. If any of these are also in yours, please let me know.
I have other interesting info from a book I am reading, on language use which I will put in a separate post.
Regards
Denise
