Cristóbal Gallego was listed on the 1540 muster as a horseman. He was mostly likely the man sent by investor Guido de Lavezariis to act as his agent. It is possible that the documentary record is lacking for this expeditionary because he accompanied Guido to the Philippines immediately upon his return to Mexico.
