Collacombe is an historic manor in the parish of Lamerton, Devon, England. The manor house survives as a grade I listed building, known as Collacombe Barton or Collacombe Manor (House). Descent d'Aumale The Domesday Book of 1086 lists COLECOME as part of the triple-manor of Ottery-Collacombe-Willestrew, the second listed of the 17 Devonshire holdings of Robert d'Aumale one of the Devon Domesday Book tenants-in-chief of King William the Conqueror. He held it in demesne. The triple group had been held before the Norman Conquest of 1066 by three Saxon thanes, including Oslac and Burgred, as four manors. It was administered within Lifton hundred after 1066. Courtenay The Devonshire lands of Robert d'Aumale later formed part of the very large feudal barony of Plympton, whose later barons were the Courtenay family, Earls of Devon. The Book of Fees (1302) lists Collecumb and Willestre as held from the honour of Plympton, the third part of the triple-manor, Ottery, having dropped out of the grouping since being given to Tavistock Abbey by one of the predecessors of Ralph d'Aumale. de Esse In 1242 it was held by Raph de Esse. Trenchard In 1295 it was held by Sir Michael Trenchard, and in 1301 by Walter Trenchard. William I Trenchard held it in 1314 and William II Trenchard held it in 1345. The last in the male line of Trenchard left a daughter and heiress, Isabella Trenchard (d.1408), who married Thomas Tremayne of Carwithenack in the parish of Constantine, Cornwall, and the manor of Collacombe passed to her descendants from this marriage. She survived her husband and remarried to Sir John Damerell, who by apparent coincidence was of the same family as the Domesday Book holder Robert d'Aumale (alias d'Amarell, Damarell, etc., Latinised to de Albemarle, de Albamara, etc.). As Sir John Damerell died without progeny he bequeathed to his wife and her progeny by her first husband Thomas Tremayne, the manors of North Huish, Sydenham Dammarel and Whitchurch. Tremayne The Tremayne (originally de Tremayne) family originated at the manor of Tremayne in the parish of St Martin in Meneage, Cornwall, about 8 miles south-west of Penryn, from which they took their surname. Thomas Tremayne Thomas Tremayne of Carwithenack in the parish of Constantine, Cornwall, who married the heiress of Collacombe, was the second son of Richard de Tremayne (d.1354) by his wife Mary Erney, a daughter of Sir Thomas Erney of Cornwall.
