Esteban Nieto and Ana Rodriguez aka Diaz

The discussion regarding the Nieto Corona's got me looking at my Nieto line which originates in Valle de Armadillo, SLP with Esteban Nieto and Ana Rodriguez she is also listed as Ana Diaz. One of their sons Agustin Nieto married 3 times. First to Angela del Castillo on 2 July 1691 in Armadillo, second to Felipa de Cervantes 11 September 1703 and lastly to my 6th great grandmother Maria de Villalobos on 11 February 1714 in Aguascalientes. From this couple I descend from two of their sons, Francisco Javier and Jose Agustin. Francisco Javier married Eugenia Ruiz de Esparza on 27 April 1755 in Aguascalientes. Jose Agustin married Rosalia Ruiz de Esparza (sister of Eugenia) on 3 June 1753 in Aguascalientes. Both Eugenia and Rosalia are daughters of Jose Miguel Ruiz de Esparza and Josefa Manuela de Chavez. Does anyone have information on the parents of Esteban Nieto and his wife Ana Rodriguez?

Thanks
