General Pedro Rodriguez Triana, on his wedding day with Herlinda Levy on June 5 1916 in San Miguel del Mezquital Zacatecas.I need to do more research but I think the full name of Herlinda Levy was Levy Abadi. General Rodriguez was active in the agrarian revolution in Mexico and later on was the governor of the state of Coahuila. He was also a candidate for the Mexican presidency representing the Communist Party of Mexico in 1929.The general had dealings with I suppose were his brothers in law or other relatives of Herlinda, Gustavo Levy and his brother Maximiliano I think with mines and other businesses in Monterrey NL, Torreon, Coah, and Camargo, Chih.I have not identified the other persons in the picture.
