Miguel de Santiago stated in 1547 that he had intended to join the Expedition but fell ill and could not go. In his stead, he sent Juan Muñoz, who unfortunately died at an unknown location in the course of the Expedition. Miguel was a native of Alcáçar de Consuegra (Ciudad Real province) and the son of Francisco de Santiago and María de Montoya Ramírez. He was able to serve in the Mixtón War.
