I am looking for any information on my great-grandmother. Her name was Lugarda Curiel and she was born in Rayon, Sonora in 1869. I haven't been able to trace back any further than her. She married John Henry Myers and had 9 children; 6 girls and 3 boys. She also had a niece named Guadalupe.
She moved to the US, El Paso I think, then to the Los Angeles California area, where she died in 1939.

Any and all help, including names, dates, places will be greatly appreciated.

Thank you;

A search for Lugarda Curiel in Rayon, Sonora, in the FamilySearch.org site - under "Search Pilot" - shows her baptism on 10 Feb 1870 in Rayon. Parents were Francisco Curiel and Leocadia Pacheco.

I also did a search just using Curiel in Sonora and there was one other entry for Rayon with the same parents: Maria Matilde, baptized 1 March 1867. There were Curiels in Arizpe in the mid 1700s. Your grandmother's family might have lived there before going to Rayon
