Lope Gallego was present at the 1540 muster and served directly under Vázquez de Coronado. It is possible that Lope was among the group of fellow expeditionaries, Rodrigo Simón and possibly Diego Gallego, who accompanied the royal treasurer Alderete to New Spain. There is very little mention in the documentary record of Lope which may be due to possibly having been killed by Natives in Oaxaca in 1546.
