My query pertains to the Maria Isidora de los Dolores Saiz, wife of Jose Ambrosio Madrid, whom you mention in several posts.
I've been tracking a rather mysterious lady who died in a housefire 18 Oct 1936 at her home in Liberty, Maricopa County, Arizona.Her death certificate states she was born in Las Vegas, NM with date of birth unknown.But based on on censuses of 1900, 1910, 1920 and 1930, her year of birth would have been about 1846/1847.Her father's name is listed as "Sise" on the death certificate - her mother's name as unknown.The censuses indicate this was her second marriage and that it occurred abt 1885/1886.According to "lore" they were married in Fort Sumner.
So in time and space this lady matches pretty closely your Isidora.Actually she's the only one that does.Here's a rough summary of your Isidora in the early census:
In 1850 La Cuesta, San Miguel, New Mexico Territory, she is Isadora, age 4, in household of Manuel Sains and Clementa.
In 1860 El Cerrito, San Miguel, New Mexico Territory, she is Isadora, age 12, in household of Manuel Saez and and M. Estrada.
In 1870 El Serrito, San Miguel, New Mexico Territory, she is Isadora, age 20, in household of Manuel Saenz and Clementa.
In 1880 La Cuesta, San Miguel, New Mexico, she is Isadora, age 28, wife of Ambrosio Madrid, with 3 children, Ramon, Blas, and Luciana.Also in 1880 La Cuesta, San Miguel, New Mexico, are her parents Manuel Sais and Clementa (age 68 and 60 respectively).It took three decades for the census taker to get their names right or almost right.
Could my mysterious Isidora Sise be your Isidora Saiz/Sais?
Have you any record or lore of what became of Ambrosio Madrid and Isidora?
