O'Carroll
O'Carroll (Irish: Ó Cearbhaill), also known as simply Carroll, Carrol or Carrell, is a Gaelic Irish clan which is the most prominent sept of the Ciannachta (also known as Clan Cian). Their genealogies claim that they are kindred with the Eóganachta (themselves led by the O'Sullivans and MacCarthys), descended paternally from Ailill Aulom.
