Aaron Green Milstead and Leonardo Villarreal were business partners and jointly owned/ran a sugarcane plantation and mill in the RGV between Santa Maria and Progreso and the Rio Grande (Rio Bravo). The families' homes were in Santa Maria, just off Old Military Highway (US 281). If you know where the old church, Our Lady of the Visitation, also known as "Chapel of Santa Maria", is on the right of the Military Highway going West, just look to your left about a mile up before you get to the Hidalgo County line, and that's where their plantation, mill, and business was. Leonardo's son, JM Villarreal, married Victoria Milstead, youngest daughter of Aaron Green Milstead. It seems like it was MORE than a marriage of business partnership convenience between the two men/families...their marriage lasted from 1870 until JM's death in 1926. They had eight surviving children
