The expeditionary Juan de Ribadeneyra most likely is the individual who was a native of Espinosa de Los Monteros (Burgos province) and the son of Francisco Fernández and María de Novara. If correct, then Juan came to Mexico in 1537. He was present at the 1540 muster as an unassigned horseman. Quite possibly he returned to Culiacán after the conclusion of the Expedition.
