My family are descendants of Espidirion Aguilar, his son Ciriaco was my Grandmother's father. They are from Pinos, Zacatecas. They had a hacienda in Pinos, first they did mining and then the Aguilar brohters had a chain of meat markets in San Luis Potosi, Aquascalientes and Zacatecas. Nicolas Aguilar was the President of Pinos I believe in the 50,s his children still have Aquilar Market and still live in town. I am sure anyone with the name Aguilar from Pinos is my kinfolk.
