Hugh is the English-language variant of the masculine given name Hugues, itself the Old French variant of Hugo, a short form of Continental Germanic given names beginning in the element *hug- "mind, spirit" (Old English hyġe). . The Germanic name is on record beginning in the 8th century, in variants Chugo, Hugo, Huc, Ucho, Ugu, Uogo, Ogo, Ougo, etc. The name's popularity in the Middle Ages ultimately derives from its use by Frankish nobility, beginning with Duke of the Franks and Count of Paris Hugh the Great (898–956).
