Roger, called de Toeni or de Conches; born probably c1104; married Ida, daughter of Baldwin III, Count of Hainault, and died between autumn 1157 and the beginning of 1162. [Burke's Peerage]
----------------------
ROGER DE TOENI III, styled also DE CONCHES, 1st son and heir, was born probably about 1104, and succeeded his father about 1126. In 1131 he attested Henry I's pancarte confirming all the grants of his ancestors and himself and others to the abbey of Conches. He is said to have waged war with Hugh de Chateauneuf in 1133. In 1135 the King suspected that he was preparing to rebel, together with William Talvas, Count of Ponthieu, on behalf of Henry's son-in-law, Geoffrey Plantagenet, and sent his own soldiers to garrison the castle of Conches. After the King's death Roger supported Geoffrey and his wife the Empress Maud against Stephen. After Easter 1136 hostilities began between him and the King's generals, the twins Waleran, Count of Meulan, and Robert, Earl of Leicester; and civil war raged in May and June. In the autumn the fighting flared up again; but on 3 October Roger was ambushed and captured by Count Waleran and Henry de la Pommeraye. His land was laid under an interdict and he was kept in prison for more than 6 months, but was released in 1137. In May 1138 he was attacked by the Count of Meulan and William d'Ypres, but defended himself successfully; and on 7 September he captured Breteuil and burnt the town. However, before the end of 1138 he made peace with the twin Earls, who conducted him to England, where he was reconciled to King Stephen. Nothing is known of what happened to his English lands during this period. In 1150 or 1151 he was with Henry, Duke of Normandy, at Rouen. After Henry had become King, Roger enjoyed the royal favour; for between Michaelmas 1157 and Michaelmas 1158 the King granted him 100 solidates of land at Holkham, Norfolk. He was a benefactor to the abbeys of la NoI, Conches and Bec.
He married Ida, daughter of BALDWIN III, COUNT OF HAINAULT, by Yolande, daughter of Gerard, COUNT OF GUELDERS. With her he had in marriage from Henry 120 librates of land out of the royal demesne at East Bergholt, Suffolk. He died after Michaelmas 1157 and probably before 1162.

Roger de Toeni [the third of that name, or III] was born ca. 1104, and died after Michaelmas 1157, presumably before his son died in 1162. He married Ida of Hainault, daughter of Baldwin III, Count of Hainault, by his wife Yolande de Guelders. It is not known when Ida died, but she presumably survived him, as Henry II granted her [Ida de Tounay] land at Garsington, co. Oxford [Rot. Hund.].
This couple had four known sons:
(1) Ralph de Toeni [V], who succeeded his father and died 1262/3, having married Margaret de Beaumont.
(2) Roger de Toeni, Jr., dead by 1185, when his wife Ade/Alda de Chaumont was holding land at Holkington, co. Norfolk, of her son Baldwin de Toeni [II] (1170-1216), Seigneur de Acquigny, apparently father of Roger de Akeny and Sir William Dakeny [Acquigny]. The Rotuli de Dominabus states that Ade/Alda was born about 1155, and that she had five daughters aside from her son Baldwin. [Does anyone have any Dakeny ancestry?]
(3) Baldwin de Toeni, who settled in Hainault [having resided with his uncle Baldwin IV], where he died in 1170, leaving issue.
(4) Geoffrey de Toeni, a cleric who flourished 1157-62, 1177.
Two daughters have also been mentioned before:
1) Goda (c1136-) m Walchieline de Ferrers
2)Godeheut de Toeni (-<1186) m William de Mohun (<1143-1176); Of Dunster; s
of William by Agnes de Gaunt. They left Agnes and Yolante
