We prefer the Hernando de Castroverde who obtained a license for New Spain in 1536. If our assumption is correct, then he was born in Medina de Rioseco in the modern province of Valladolid to Alonso de Castroverde and Isabel Requexón. His birthplace was a town under the control of a Mendoza family member, another reason to assume this is our expeditionary. He also was a hosier, a skill much needed on the expedition. He served in the company of don Rodrigo Maldonado. He may have married Beatriz de Galvés and died before 1550.
