RE: CRUZ SANCHEZ
I don't know that this is the person you are seeking, but in the Holy Trinity (Trinidad, CO) Baptisms 1866-1870, compiled & translated by Dr. E.L. Torres, there is a baptismal record for JOSE de la CRUZ SANCHEZ, baptized 3 Mar 1869, son of Jujan [sic] (Julian?) Sanchez de San Francisco & Rosario Mestas. Godparents: Julian Mares & Brigida Sanchez.
(Note: San Francisco, E or W of Trindad?).
I did not see a record for Cora Martinez in this publication of baptisms.
