Born at Kilkea Castle and never married but was educated at Eton College,[1] he acceded to the dukedom and its related titles upon his father's death from typhoid fever in 1893, at age 42;[2] his mother died of tuberculosis in 1895, at age 30.
During his minority, his family's large estates in County Kildare were sold in November 1903 by his trustees to 506 tenant farmers via the Land Commission. Some of the lands had a title dating back to the Norman invasion of Ireland in 1171. The 45,000 acres sold for £766,000, a huge amount at the time, but this had to cover costs, some mortgages and £272,000 that was earmarked to family trusts for the surviving younger children of the 4th duke.[4]
The 6th Duke was reported to be in delicate health from childhood onwards and, the day before he turned 21, in 1908, a newspaper observed that he was "little known in London", due to the "careful way in which he has been obliged to live".[5] Actually, the young Duke was, at the time, a patient at Craig House Hospital, a psychiatric institution, in Edinburgh, Midlothian, Scotland; there he lived in his own villa, attended by a butler, from 1907 until his death in 1922.[6][7][8]
From 1908 until death John Donald Pollock served as his personal physician and confidant.[9]
