I have recently come across a ancestor who went by the surnames either Ruiz de Esparza, Esparza or Salado. It seems to originate from Bernardo Ruiz de Esparza who married Catalina Losano in the early 1600's In some cases he is called Esparza, Salado or Ruiz de Esparza. His one son Agustin does this as well and possibly another son Christobal. I know about the Lope Ruiz de Esparza's family as I already decend from them, but now I have this monkey wrench thrown in. Does anyone have an idea to why they went by Ruiz de Esparza and Salado?
