Santiago Jiron was baptised at Cochiti on Aug. 2, 1830, son of Jose Antonio Jiron and Maria Juana Hurtado.The paternal grandparents were listed as Nicolas Jiron and Juana Aragon.The maternal grandparents were Miguel Hurtado and Francisca Lucero.
I was puzzled regarding Juana Aragon as a wife of Nicolas, because I had seen his wife listed as Juana Paula Lucero (md. Apr. 20, 1790).Nicolas married first to Rosa Manzanares, but I don't have a date for the marriage yet. In looking further, I saw Juana Paula Lucero listed in baptismal records earlier on as a parent with Antonio Aragon.I think he died and she used his name in Santiago's baptismal record.Juana Paula Lucero, bapt. Jan. 30, 1778 at Cochiti, is the dau. of Miguel Lucero and Maria de la Luz Sandoval
Nicolas Aragon was the son of Francisco Aragon and Juana Aragon/Mendoza, baptised at Cochiti on Sept. 21, 1756.
The ancestry of Miguel Lucero and Francisca Lucero can be found in The Families of Lucero de Godoi by Margaret Buxton, but you can also find Miguel Hurtado/Francisca Lucero's ancestry submitted on the Great New Mexico Pedigree on the HGRC website.
