Haro and Robles of Zacatecas

My twin sister and I first began researching our family history four years ago. We have found a lot through Ancestry.com and FamilySearch.org. My Great Grandmother, Aurelia Haro Robles emigrated to The United States with her mother from Mexico March 26, 1929. She was born July 19, 1916 in Rancho La Nopalera, Mezquital del Oro, Zacatecas.

Her parents were Jose Doroteo Haro, of Mezquital del Oro, Zacatecas, and Maria Esther Robles of Zacatecas, Zacatecas. Not much is known of Maria’s parents, but I have traced Jose’s to the early 1800’s, each generation from is parents (Pedro Pascual Haro Haro and Agapita Banuelos Villarreal) on are born in Moyahua de Estrada, Zacatecas.

I am looking for more info on Maria Esther Robles’ family (her parents names were E. Higinio Robles and Juana Miramontes) and anything on Rancho La Nopalera, Mezquital del Oro, Zacatecas. Maria Esther also had twin daughters born in Mexico who I know nothing about.
