English : habitational name from any of the numerous places so named, in northern France as well as in England. These are named with the Old French elements riche ‘rich’, ‘splendid’ + mont ‘hill’. Richmond in North Yorkshire was named after a Richmont in France immediately after the Norman Conquest, and in many if not most cases the English surname can de derived from this place. Richmond in southwest London received this name only in the reign of Henry VII, in honor of the king, who had been Earl of Richmond until he came to the throne, and is unlikely to be the source of this surname.
