Early Barons Inchiquin  There were six early Barons Inchiquin in Ireland between 1543 and 1654. The title was granted to Murrough O'Brien, the brother of Conor O'Brien, King of Thomond, when he surrendered his Irish royalty to King Henry VIII in 1543. His descendants held the title until 1654, when Murrough O'Brien, 6th Baron Inchiquin was created Earl of Inchiquin. Murrough O'Brien, 1st Earl of Thomond and 1st Baron Inchiquin (died 1551) was the son of Turlogh O'Brien (Toirdelbach Ua Briain), Prince of Thomond (died 1528) and Raghnailt Macnamara, daughter of John Macnamara. His father was the son of Teige An Chomard, King of Thomond. He took the crown of Thomond on the death of his brother Conor 1540, but surrendered power to Henry VIII after the Irish Parliament passed the Crown of Ireland Act 1542, making his submission in 1543 in London, where he was created an earl. Murrough O'Brien married Eleanor FitzGerald, daughter of John FitzGerald, Knight of Glin. Murrough O'Brien was succeeded in the earldom of Thomond according to a special remainder by his nephew Donough. His son Dermod was the 2nd Baron Inchiquin in the tail male. His other children were Donough, Teige and Torlogh. Dermod O'Brien, 2nd Baron Inchiquin (d. 1 May 1557) was the son of Murrough O'Brien, 1st Earl of Thomond and his wife Eleanor FitzGerald. He married Margaret O'Brien, daughter of Donough O'Brien and Slany MacNamara, before 1550. His son Murrough McDermot was the 3rd Baron Inchiquin. Murrough McDermot O'Brien, 3rd Baron Inchiquin (1550–1574) was the son of Dermod O'Brien, 2nd Baron Inchiquin and his wife Margaret O'Brien. He married Margaret Cusack, daughter of Thomas Cusack, Lord Chancellor of Ireland. His son Murrough was the 4th Baron Inchiquin. As late as 1559, we hear that the O'Bryans and others Irish peers could understand no English, and required the services of the Earl of Ormonde to translate the learned speeches of Sir Thomas Cusack into their tongue.
