Lord Inchiquin, an Irish representative peer, died on Monday at Dromoland Castle, Co. Clare, at the age of 65.

Lucius William O'Brien, the eldest son of the 14th baron, was born at Bishop Waltham, Hants, on June 21, 1864. He went to Eton in 1878, to the Rev. Edward Hale's house, and left in 1880.

In 1885 he contested East Clare as a Conservative. He held a commission in the Rifle Brigade from 1885 to 1893, and in 1895 was appointed State Steward to the Lord Lieutenant.

In 1898 he was High Sheriff of Co. Clare. On the death of his father in April, 1900, he succeeded to the Irish baronry created in 1543, and to the baronetcy created in 1686.

This family of O'Brien is shown in the "Complete Peerage" as descended from Murrough O'Brien, Prince of Thomond, who in 1514 resigned to King Henry VIII. his "captainship, title, superiority, and country", and was created Earl of Thomond.

Many members of the family later distinguished themselves, notably the first Earl of Inchiquin and the first Marquess of Thomond, dignities which are now extinct.

Lord Inchiquin succeeded his father as a representative peer in 1900, and also became honorary colonel of the Clare R.F.A. Reserve. He was a good sportsman and a good resident landlord, owning over 20,000 acres, and was very popular with his tenants.

During the troubles after the War he was not interfered with. On the establishment of the Free State he became a member of the Senate. He was president of the Ennis branch of the British Legion, and took an active interest in its work.

Lord Inchiquin married in 1896 Ethel Jane, elder daughter and co-heir of Mr. Johnstone J. Foster, of Moor Park, Ludlow, and Cliffe Hall, Lightcliffe, and had three sons and three daughters.

He is succeeded by his eldest son, the Hon. Donough Edward Foster O'Brien, was was educated at Eton, Sandhurst, and Magdelen College, Oxford, and served in The Rifle Brigade in the War.
