GeneralDomesday tenant of William de Picquigny.
Notes for Otbert de Merck
Jenkins in Appx C of the Missenden Cartulary asserts that Otbert must have been the father of Reinerus de Lohering. Keats-Rohan mentions this in Domesday People but does not confirm it though she does say that Reinerus succeeded Otbert in his Bucks holdings; she says also that Otbert was the “Father of Adelolf de Merck, an important tenant of Eustache de Boulogne in 1086”.
My thought is that Reinerus could as easily have married a daughter of Otbert.
DP says he was a Fleming from Marck-saint-Levin, Pas-de-Calais, comm. and cant. Fauquembergues in Artois. He was a Domesday Tenant of William de Picquigny in Northants and possibly also in Bucks.
