clan in county Down became knights, and the O'Byrnes of Wicklow, the Kavanaghs of Wicklow, Cahir, Baron of Ballyane Lords of Ballyane, the O'Donnells of Donegal were others who accepted the system. The O'Donnell chief was created an earl briefly by James I of England in 1603–07. The Clanricarde Burke took the title of earl in 1543. The O'Shaughnessys of Gort and the O'Driscolls of Corcu Loígde also became knights. Ruairí Caoch Ó Mórdha (Rory O'More; the father of Rory O'More) of Laois surrendered and was regranted in 1542–43 but died in 1545. His clan was out of favour by 1550; in 1556 Laois was shired as the "Queen's County". Other clans such as the MacMahons of County Monaghan did not take part in the new system. Tibbot ne Long Bourke, the heir of "Lower MacWilliam Burke" lands in County Mayo, and a son of Gráinne O'Malley, remained outside the system until 1593; he was knighted in 1604 and was created the first Viscount Mayo in 1627. Gráinne herself accepted the system in 1576, in respect of her own lands, though she managed her lands with a high degree of autonomy over the next two decades. Donnel O'Donovan, chief of the largest sept of the O'Donovans of County Cork offered a surrender of their sept lands in 1592 (with similar offers by Conoghor O’Kallaghane, Conoghor O’Mahoney and Teig M’Owen Carty), to personally receive back the sept lands by patent. The surrender to Queen Elizabeth was not effected until 1608, to James I; Donnel O'Donovan received the sept lands as his personal estate in 1615, but did not receive an English title. The overlord in the Barony of Carbery to Donovan of Clan Cathail, the MacCarthy Reagh, who surrendered his sept lands in 1606, also never received any titles under this system. Donal McCarthy Mór was knighted in 1558 and created Earl of Clancare in 1565, but resigned his titles in 1597. The prominent MacCarthys of Muskerry, a separate dynasty, were later created the Viscounts Muskerry in 1628 and Earls of Clancarty in 1658. The chief of the Maguire clan of Fermanagh was created Baron Maguire in 1628. In 1631 Sir Terence Dempsey was created Viscount Clanmalier. Randal MacDonnell was knighted in 1602, was granted estates in 1603 and was created Earl of Antrim in 1620. Effect on Irish heraldry Because of the number of new lords in the Irish House
