Olinger is an ancient Norman name that arrived in England after the Norman Conquest of 1066. The name Olinger comes from the name of the famous St. Leger.
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 (898â956) .
