Guatimozin is a variant of Cuauhtemotzin, itself another version of the name Cuauhtemoc. Cuauhtemoc originates in Native American languages and means "one who falls like an eagle". This was the name of the Aztec ruler of Tenochtitlan, the capital of the Aztec Empire, in the 15th century. As a masculine given name, Guatimozin is very rare in the United States these days.
