Norma, my ggrandmother was Rosario Mendivil. She was born around 1850-1860, and married my ggfather Gregorio Escandon around 1870. They lived in La Trinidad, Sonora, in the 1880s where my gfather Antonio was born, and then moved to Cananea, Sonora, where I guess she passed away before my mother Isaura was born in 1914. I would appreciate it if you pass along any info you might find about her, that is if you run into her name. Thanks.
