We are related to the Felipe Siqueiros line and Maria Loreta de Olea. They were from San Antonio de las Huertas, Sonora, Mexico. I was wondering if anybody might have any information about approximate dates of birth. I am interested in hearing from any Siqueiros'. His son was Ignasio Siqueiros born in about 1800 in San Antonio de las Huertas, Sonora, Mexico. He died in Chihuahua. They were some of the original inhabitants of Ocampo, Chihuahua, Mexico.
