The van Gent name has a number of variants, including Gand and Gaunt.
- Hugues IV had at least three children. Cawley and Burke's Peerages differ in the number and names of the children. According to Burke, Robert de Montfort, eldest son of Hugues IV, did not have offspring and was succeeded by his brother, Thurstan, who built a castle Beaudesert (Beldesert) in Warwickshire and that line is known as de Montfort of Beaudesert.
- Thurstan de Montfort of Beaudesert was succeeded by his son, Henry de Montfort.
- It is speculated that Henry de Montford had a younger brother, Thurstan, who became Thurstan de Charlecote. A discussion can be found in Shakespeare's Warwickshire Contemporaries by Charlotte Carmichael Stopes.
"Sir Thomas Lucy came of a long line of distinguished ancestors, who had dwelt at Charlecote over 400 years, and had given commanders, councillors, sheriffs, knights of the shire, and justices of the peace repeatedly to the service of their country. Dugdale supposes Thurstan de Charlecote to have been a younger son of Thurstan de Montford, whose son and heir Henry granted to Walter the son of Thurstan of Charlecote the lordship of the village, which grant King Richard I. confirmed by letters natent at Dover 6th Dec., 1191, and John again confirmed with all the privileges therein noted in his fifth year. "From this Walter de Charlecote (who was a knight) by Cecily his wife, descended William, who assumed the surname of Lucy." This makes Dugdale think that his mother Cecily* must have been a "Lucy.""
