William De Ow

William De Ow was a Norman noble and a cousin of William the Conqueror. At the time of the Domesday Book he was a landholder in Dorsetshire, Gloucestershire, and Somerset, and he was the owner of what is now known as Stonehouse Manor, a grade II listed manor in the Cotswolds town of Stonehouse, Gloucestershire.

Thomas Cox's Magna Britannia, Antiqua et Nova (ca. 1738) states that, during the reign of William Rufus, De Ow was accused of treason and demanded to prove himself innocent via trial by combat. He lost and was subsequently blinded and dismembered.
