James King, 5th Earl of Kingston

After the death of his troublesome elder brother Robert in 1867, King succeeded to his family's titles and their seat at Mitchelstown Castle in the north of County Cork.

Lord Kingston died at Mitchelstown Castle in September 1869, aged 69.

He left no children and his junior title of Baron Kingston died with him.

He was succeeded in the remaining titles by his kinsman Robert King, 2nd Viscount Lorton, who became the 6th Earl.

Kingston's wife and sole heir to his estate, now styled the Dowager Countess of Kingston, continued to live at and manage the crumbling affairs of Mitchelstown, aided from 1873 by her second husband, William Downes Webber, of Kellyville, Queen's County.
