[Line from "The Plantagenet Ancestry," W.H.Turton (Balt.: Gen. Pub. Co., 1968), p. 88, 100:] Gilbert "accompanied his uncle [William the Conqueror] into England, and participating in the triumph of Hastings, obtained a grant of the lands of a Danish
proprietor, named Tour, with numerous other lordships. This Gilbert happened to be in York, anno 1069, and had a narrow escape, when the Danes, in great force on behalf of Edgar Etheling, entered the mouth of the Humber, and marching upon that city,
committed lamentable destruction by fire and sword, there being more than 3,000 Normans slain. Like most of the great lords of his time, Gilbert de Gant disgorged a part of the spoil which he had siezed to the churches, and amongst other acts of piety
restored Bardney Abbey, co. Lincoln, which had been utterly destroyed many years before by the pagan Danes, Inquar and Hubba." - Burke's "Dormant and Extinct Peerages," 1883, p. 227. Gilbert is "son of Baldwin, Earl of Flanders, by Maud, sister of
William the Conqueror".
