Idoine (or Idonea) de Camville was born c. 1209 in Brattleby,
Lincolnshire, the only daughter and heir to Richard de Camville, who in
turn was the only son and heir of Gerard de Camville and Nicola de la
Haye, holders of the castellanship of Lincoln Castle.
The de Camville family came to England with William the Conqueror in
1066 and until the loss of Normandy in King John's reign still held
Canville-les-Deux-Eglises, from which they took their name. Richard de
Camville's largest estate, and what is believed to be the head or caput
of his Barony, was at Middleton Stoney in Oxfordshire although he also
held in chief Avington in Berkshire and Godington in Oxfordshire. In
1215 Idoine's mother died and her father sided with the barons in the
civil war, despite her grandparent's long standing allegiance to King
John. The year after Magna Carta was signed her father had his lands
seized by the crown and the castle at Middleton Stoney was destroyed on
the King's orders.
Idoine was taken into Royal custody in Corfe Castle where her wardship
was sold by the King to William Longespée, Earl of Salisbury. It was
arranged that she should be married to his son William Longsword who,
like Idoine, was still a child at the time. With her wardship William
Longespée obtained the custody of all the lands which belonged to Idoine
by right of her mother Eustachia, the daughter of Gilbert Basset, Lord
of Bicester.
She had married William Longsword and attained her majority before June
1226, when the King returned to them the lands of Richard de Camville,
who we assume by this time had died. This meant that the lands inherited
by Idoine from the Basset, de la Haye and de Camville families were now
in the hands of the Longespées, making it a very profitable marriage for
William. It is believed that they may have had four children (William,
Richard, Ela and Ida), although the only ones well recorded are William
and Ela. Idoine died c. 1251, a couple of years after her husband's
death at the Battle of Mansor.
