Romeo Family History

Italian: from the personal name Romeo, which derives ultimately from the classical Greek adjective rhomaios (modern Greek romeos), originally denoting someone from the eastern Roman Empire, i.e. Byzantium, later someone from Rome itself, in particular someone who had been on a pilgrimage there, and finally someone who had made any pilgrimage, i.e. a pilgrim; from this last sense arose the personal name.
