The Lyons family (originally styled de Lyons, or de Leonne, Lyonne, and also spelled Lyon) is an eminent Anglo-Norman family descended from Ingelram de Lyons, Lord of Lyons, who arrived in England with the Norman Conquest, and from his relation, Nicholas de Lyons, who emigrated from Normandy to England in 1080 and was granted lands at Warkworth, Northamptonshire by William of Normandy. The family originated in the district of the Forest of Lyons, north of the town of Lyons-la-Forêt, in Haute Normandie, where their seat was the Castle of Lyons. The original surname was 'de Lyons' ('of [the Forest and Castle] of Lyons'): subsequently, the 'de' was removed from the name, and some branches removed the 's' from the end of the word, producing 'Lyon'.
