Domingo Fernández was not present at the 1540 muster. The only reference we have to his participation comes from the work of fray Antonio Tello in the 1550s and later repeated in Mota y Padilla's work of the 1700s. These authors stated that Domingo was a criado of the expeditionary Lope de Samaniego and that he died along with expeditionary Diego Alcaraz in Corazones (Mexico).
