Raoul I of Tosny

Raoul I of Tosny was Lord of Conches, and probably an heir of Raoul, brother of Archbishop Hugh of Rouen.

In 1013 or 1014 Duke Richard II entrusted him (together with his son Roger and Nigel, viscount of Cotentin) with the castle at Tillieres-sur-Avre, where he defeated Odo II, count of Blois-Chartres.

There is evidence that Raoul participated in the wars in Southern Italy, probably following a dispute with Richard. The evidence points out to his participation in the rebellion against the Byzantines in 1017, and according to Raoul Glaber he was welcomed back by Richard in 1023, after fighting alongside King Henry II of Germany against the Byzantines in 1022.

He died probably in 1026.

Family
Raoul had a son, Roger, who inherited his lands and titles.
