Much of what is known about Drogo de la Bouerer is known from the
Domesday Book of 1086, and the chronicles of
Fountains Abbey in North Yorkshire and of
Meaux Abbey in East Yorkshire. According to the Domesday record, after the
Norman Conquest Drogo held lands in and was
lord of all of Holderness, holding dozens of manors there; On discovering the lie King William sent for Drogo to be arrested, but he was never caught, and subsequently Drogo's possessions in Holderness were passed to
Odo, Count of Champagne. Odo became Lord of Holderness sometime before September 1087. ==Notes==
