They were originally from the region of Normandy and played a significant role in the feudal system, holding various lands and titles. The family is often associated with the Norman Conquest of England in 1066, as many members migrated and settled there. Members of the Tosny family were known for their military service and loyalty to the Duke of Normandy. They established several castles and estates, contributing to the political landscape of both France and England. The family's influence waned over time, but their legacy remains in historical records.
