Uinnseadún
UINNSEADÚN—XI—Unsedon, Winsedon, Wynchedon, (Nugent); Norman 'de Wynchester,' i.e., of Winchester, an ancient episcopal city in Hampshire. Members of the family of Nugent who came from this city and settled early in Cork were known in Irish by the surname Uinnseadún, which was intended to represent Winchester. These Nugents formed a clan after the Irish fashion. The chief lived at Aghavarten Castle, near Carrigaline. The original surname, Nugent, has been retained in English. Compare with Núinnseann.
