Gilbert de Tonebruge, who resided at Tonebruge and inherited all his father's lands in England, joined in the rebellion of Robert de Mowbray, Earl of Northumberland, but observing the king (William Rufus) upon the point of falling into an ambuscade, he relented, sought pardon, and saved his royal master. We find him subsequently, however, again in rebellion in the same reign and fortifying and losing his castle at Tunbridge. Hem. In 1113, Adeliza, dau. of the Earl of Cleremont, and had issue, Richard, his successor, Gilbert, Walter, Hervey, and Baldwin. Gilbert de Tonebruge, who was a munificent benefactor to the church, was s. by his eldest son, Richard de Clare.

Gilbert m. Adeliza, dau, of the Earl of Claremont, and was father of Richard de Clare, Earl of Hertford, and Gilbert de Clare, created Earl of Pembroke. [Sir Bernard Burke, Dormant, Abeyant, Forfeited and Extinct Peerages, Burke's Peerage, Ltd., London, England, 1883, p. 230, Giffard, Earls of Buckingham]

Gilbert married Adeliza (Alice) de Clermont about 1086. Adeliza (daughter of Count of Clermont Hugh de Clermont and Margaret de Roucy) was born about 1072 in Clermont, Beauvais, Oise, France. [Group Sheet] [Family Chart]

Notes:

There seems to be a serious error in line 246b-24 of Ancestral Roots, which has this Adeliza marrying Robert de Condet d. 1141, after her marriage to Gilbert FitzRichard. This does not agree with any other lines, which have Robert de Condet's wife as Adeliza dau. of Ranulph le Meschin, Earl of Chester. The error in generation 24 is shown in the next generation of this line (246b-25) which has Adeliza dau. of Ranulph marrying first Richard FitzGilbert and then Robert de Condet. I believe this (generation 25) is correct.

Notes:

GEOFFREY DE MANDEVILLE
The Conqueror and His Companions
by J. R. Planché, Somerset Herald. London: Tinsley Brothers, 1874..

This progenitor of one of the noblest and most powerful families on either side of the channel is simply alluded to by Wace as "li Sire de Magnevile" (l. 13,562).

The French antiquaries, whilst agreeing as to the individual present at Hastings, differ respecting the locality whence he derived his name; Mons. Le Prévost considering it to be Magneville, near Valonges, whilee Mons. Delisle reports that it was Mandeville le Trévières, the Normanan estates of the Magnavilles, Mandevilles, or Mannevilles, as they were indifferently called, lying partly in the neighbourhood of Creulli, and the rest round Argentan, where, at a later period, they held the honor of Chamboi.

No particular feat of arms is attributed to him by the Norman poet. He is only mentioned as one who rendered great aid in the decisive battle, and we find him in consequence rewarded with ample domains in England at the time of the great survey, amounting to one hundred and eighteen lordships in various counties, of which Walden, in Essex, was the chief seat of his descendants, who became the first Norman earls of that county in the reign of Stephen.

He was also the first Constable of the Tower of London after the Conquest, an office enjoyed by his grandson of the same name, which I mention on account of the interesting fact that, in the charter of the Empress Matilda, which confers this amongst many other honors bestowed upon him, the custody of the Tower of London is granted to him and his heirs, with the little castle there (described, in another charter as under it) which belonged to Ravenger.

This charter in which she creates Geoffrey de Mandeville (grandson of the companion of the Conqueror) Earl of Essex, is stated in a marginal note in Dugdale's Baronage to be "the most ancient creation charter which hath been ever known," and, I may add, for the numberless concessions and privileges recorded in it, the most remarkable.

To return to the first Geoffrey, we learn from his charter of foundation of the Benedictine Monastery of Hurley, in Berkshire, that he was twice married. His first wife Athelaise (Adeliza) being the mother of his heir William de Mandeville, and other children not named; and his second wife, Leceline, by whom he appears to have had no issue.

Mr. Stapleton, in his annotations to the Norman Rolls of the Exchequer, suggests that Adeliza, the first wife of Geoffrey, was sister to Anna, wife of Turstain Haldub, mother of Eudo al Chapel.

Geoffrey married Adeliza de Balts about 1057 in England. Adeliza was born about 1040 in Rycott, Oxfordshire, England; died in Westminster Abbey, London, Middlesex, England. [Group Sheet] [Family Chart]

Eudo married Rohese FitzRichard de Clare about 1088. Rohese (daughter of Richard FitzGilbert de Clare and Rohese Giffard) was born about 1055 in Tunbridge, Kent, England; died in 1121 in England. [Group Sheet] [Family Chart]
