Kirby surname meaning

Kirby is chiefly an English habitational surname from places called Kirby or Kirkby. The name combines Old Norse kirkja, “church,” with býr, “farmstead” or “settlement,” so different villages could create separate families. Kirkby preserves the fuller place-name, while Kerby and Kerwick may appear in Irish or other regional histories. Irish Kirby can be an anglicization of Ó Cíarmhaic, and not every bearer therefore has a Norse place origin. The catalog uses place for the dominant English route, with disputed confidence because the Irish personal-name history is independent and the Latin spelling alone cannot distinguish it.
