Notes:

de Lacy (Laci, Lacie, Lascy, Lacey) is the surname of an old Norman noble family originating from Lassy (Calvados). The first records are about Hugh de Lacy (1020-1049). Descendent of Hugh de Lacy left Normandy and travelled to England along with William the Conqueror. Walter and Ilbert de Lacy fought in the battle of Hastings. The family took a major role in the Norman conquest of England and Ireland. Up until 1399, the De Lacys held the great northern Lordship of Bowland before it passed through marriage to the Earldom, later Duchy of Lancaster as well as being Lords of Pontefract and later Earls of Lincoln.

The family is linked to the Scottish Royal family; Elizabeth de Burgh, whose great grandfather was Walter de Lacy, married Robert the Bruce. Another link exists to the Royal Windsor family by Sarah Ferguson via Wingfield, Meade, O'Brien, FitzGerald, De Burgh and therefore back to Walter de Lacy and Hugh de Lacy.

Hugh de Lacy (before 1040, lord of Lassy (Normandy) - 27 March 1085, Hereford). He had two sons, Ilbert and Walter, who probably fought at William's side at Hastings (see the Adalae Comitissae (To Countess Adela), by Baudri, abbot of Bourgeuil, who suggest Ilbert led the feint that led to the death of King Harold). There is no record of Walter Jnr fighting at Hastings. Ilbert was a major participant in the Harrying Of The North (1069-70, receiving vast land in West Yorkshire, where he built Pontefract Castle.
