Theodosia Bligh, 10th Baroness Clifton

Baroness Clifton was the third child and second daughter of Edward Hyde, 3rd Earl of Clarendon and Katherine Hyde, 8th Baroness Clifton. Her mother's title went first to her brother Edward Hyde, 9th Baron Clifton, but after his death from a 'surfeit of drinking',[3] she succeeded as the 10th Baroness Clifton, of Leighton Bromswold on 12 February 1713.[4]

Baroness Clifton married John Bligh, MP for Athboy, soon afterwards, on 24 August 1713 at Westminster Abbey. They had six children and Baroness Clifton died in childbirth in 1722. She was buried on 15 August 1722 at Westminster Abbey. Baroness Clifton's title passed to her second son, Edward. Her husband John was created Baron Clifton of Rathmore in 1721, and after her death was further elevated as Viscount Darnley and later Earl of Darnley in the Peerage of Ireland (Theodosia's ancestors, the Dukes of Lennox, had also been Earls of Darnley in Scotland).

The portrait called "Lady Theodosia Bligh, Countess of Glandore" painted in the manner of John Vanderbank the younger is now thought to be of her mother, Baroness Clifton. It is now in the collection of Castle Ward, County Down.[5]
