the de Carreus, or Carews, held the barony of Idrone in County Carlow, without relinquishing their holdings in Britain. William de Carreu (died 1213), held both manors of Carew and Idrone. Maurice de Carreu was in Edward 1's Irish Parliament in 1300. Raymond de Carreu appears in Irish records in 1302. Sir John Carew (d. 1362), who also held the manor of Moulsford in Berkshire, was Justiciar of Ireland. Another Norman branch, which may or may not be related to the Idrone Carews, said to be descended from Adam Montgomery de Carrew, settled in East Cork, at Garryvoe, on the Waterford border in the 12th century. This family is described in 'British Museum Funeral Certificates', MS. No. 4820. They feature frequently in the 'Fiants' (Tudor records): e.g. John Careue of Garryvoe, 1582; Redmond & Peirse Carewe, 1600. They forfeited Garryvoe, as rebels against Cromwell's 'Commonwealth' in 1656. Paul MacCotter has claimed in 'Irish Roots' (1997) that the rare East Cork Carews survive under the form 'Carey'; although the Garryvoe family definitely died out in the male line in the 1660s (Brit Mus.MS 4820); and Carey in this area is regarded as an Anglicisation of Ó Ciaráin. There is recorded evidence for Carew being used as a synonym of the Munster surname Ó Corráin/Ó Carráin. The 'Court of Claims' in Ireland, 15 July 1663, adjudicates a request for return of lands in and around Mobernan in County Tipperary forfeited by 'Teige Carrue alias O Carron'. Donald O Carrane of Mobernayne, 1586 was his ancestor. By the 17th century the Mobernan O Corrain sept had widely adopted Carew as an Anglicised form of their name: Conor Carew of Mobarnan, was a representative at the Catholic Confederation of Kilkenny, 1642. Thomas Carue (alias O Corrain) of Mobernan appears in the Dictionary of National Biography<ref>Thomas Carve, Dictionary of National Biography', Oxford University Press</ref> His brother, Sir Ross Carey, appears on the 1661 memorial of Anne Hyde, his wife, in Westminster Abbey. Carve, however, in his Lyra sive anacephalaeosis Hibernica claims that the usage of Carran for his family name is incorrect. He says "Prater hos alia est antiquae nobilitatis domus nimirum Domini Carue Imakellanse, a Thomas Carue (de quo Paulo ante tractavimus) suam protrahit parentelam, ex qua etiam aliae non ignobiles familiae excreverunt, quo abusive Hibernico Idiomate Carran appellantur. Ex his orti sunt Robertus Carve de Imakelly, & Roseus Carve de Moberman Equites aurati."
