Juan Velázquez de León was a Spanish conquistador, who along with Hernán Cortés participated in the third Spanish expedition to continental America (present day Mexico) in 1519.^[1]: 50 He was distinguished by being relative of the then Governor of Cuba Diego Velázquez, but overall served Hernán Cortés and the cause of the Conquest. Cortés gave Juan the daughter of Maxixcatzin, baptized as Doña Elvira, after the Tlaxcallan's made peace with the Spanish.^[1]: 178
