Barnett is a masculine name of Anglo-Saxon and Old French origin. The meaning of Barnett is 'the clearing of woodland by burning'. It came to be in the aftermath of the Norman Invasion. Barnett is more common in Scotland, while its variant Bernard is more common in England. It is derived from the Old-English word Beorna, meaning 'warrior', and the Old French word Barnet, meaning 'little one'. Bearnard was introduced to England by the Normans in the form of Bernard. The name was common in medieval England and eventually spread to other parts of the British Isles. But it is still fairly common in the United Kingdom today.
