------------------------
RALPH DE TOENI IV, styled also DE CONCHES, 2nd but 1st surviving son and heir, assented with his mother and his elder brother, Roger, to his father's gifts to St. Evroul. He succeeded his father probably in 1102; and in 1103 he was one of the nobles who supported the claim of Rainald de Grancei to succeed to the Barony of Breteuil on the death of William de Breteuil. In the same year he was a member of the alliance formed by Robert, Count of Meulan, to force Goel d'Ivri to release his burgher, John of Meulan. He then crossed to England and, being graciously received by the King, obtained his father's lands; and in 1104 he returned to Normandy with Henry, as one of his ardent supporters. He was in the King's army in Normandy in 1106 and took part in the battle of Tinchebrai on 28 September. In 1110 he was with the King at Romsey. When rebellion broke out in Normandy in 1119, he remained faithful to Henry. About the same time by the King's advice Ralph de Gael gave him Pont-St.-Pierre and the whole valley of Pistres. In 1120 he was with Henry at Rouen. He was a benefactor to the abbeys of Bec and Conches, and perhaps to the priory of Westacre.
He married, in 1103, in England, Alice, younger daughter and coheir of Waltheof, EARL OF NORTHUMBERLAND, NORTHAMPTON and HUNTINGDON, by Judith (the King's cousin), daughter of Lambert, COUNT OF LENS. Alice inherited Walthamstow, Essex. Ralph died about 1126 and was buried at Conches. His widow gave the church of Walthamstow to Holy Trinity, London, for the salvation of the souls of her son Hugh, who was buried there, and her husband.
