The Barony of Carrington has been created thrice: once in the Peerage of England, once in the Peerage of Ireland and once in the Peerage of Great Britain. The first barony (which was held along with a Viscountcy) ended in extinction while the remaining two are extant and united under a single holder.
The third Baron Carrington was also created, in the Peerage of the United Kingdom, EarlCarrington and Viscount Wendover, of Chepping Wycombe in the County of Buckinghamshire, in 1895 and Marquess of Lincolnshire in 1912.
The sixth Baron Carrington was also created a life peer as Baron Carington of Upton, of Upton in the County of Nottinghamshire, (spelled with a single "r") in the Peerage of the United Kingdom.
The present Barons Carrington are related to the Barons Bicester.
