Yoli,
I found your great grandparents marriage record today at my local family history center as this film is on permanent loan. LDS Film # 0226733. They were married 3 May 1871. Rosalio Jauregui, soltero de veinte un años, 21 years of age, originario y vecino de La Estancia, meaning Rosalio was from La Estancia, legitimate son of Salvador Jauregui who was living and Carina or Corina Vidaurre who was deceased. Pomposa Gonzales, celibate 16 years of age, also from La Estancia, legitimate daughter of Nicomedes Gonzales & Anastacia Saldivar both of whom were still living. Their padrinos were Leon Vidaurre and Francisca Jauregui. Witnesses were Antonio Ballin & Sixto Duran.
