Selwyn

Selwyn is originally an Anglo-Saxon name, also occasionally spelt Selwin, deriving from 'Sel' (castle/house) & 'wyn/win' (friend), roughly meaning "friend in the house" or "friend in the castle".

The name Selwyn later became an English surname as well after the Norman Conquest of 1066 introduced the concept of family surnames to England. Its renewed popularity as a Christian-name in England in the 19th century was largely due to the fame of the eminent Bishop George Augustus Selwyn.

Selwyn is quite uncommon as both a first name and family name.
