In An Infamous Mistress: The Life, Loves and Family of the celebrated Grace Dalrymple Elliot, we mention her uncle by marriage, John Dundas who married Helen Brown, Grace’s determined and strong-minded maternal aunt who was a constant presence in Grace’s formative years. In 1748, some six years before Grace was born, John Dundas was a Captain in the 34th Regiment of Foot and was placed in command of a troop of soldiers hunting two fugitives from Newgate Prison.
William Gray and Thomas Kemp had been arrested for smuggling, both members of the notorious Hawkhurst Gang of smugglers and thieves who terrorised the south coast of England from Kent to Dorset during 1735 to 1750. On the 30th March 1748, these two, along with five other smugglers who were all being held in Newgate, managed to escape, all taking different routes through the London streets. Five of them were soon taken, but Gray and Kemp got clean away. They evaded capture for some weeks until, in mid-May, the following report appeared in the newspapers:
By an Express from Hastings we have an Account, that William Gray, who lately broke out of Newgate, was last Tuesday Morning retaken by a party of Lord Cobham’s Dragoons, under the Command of Capt. Dundass, of Cholmondeley’s Regiment of Foot and carry’d to that Place; and that Kemp, who broke out at the same Time with Gray, narrowly escaped being taken with him.
William Gray stood trial and was sentenced to be transported for seven years; the Penny London Post reported on 27th July 1748, that Gray had given the Government information regarding smugglers and he was to be pardoned, however, he remained in Newgate and the General Evening Post, 19th November 1748 mentioned that he was so ill his life was despaired of. Thomas Kemp was recaptured along with his brother in 1749, after breaking into a house armed with pistols; both were sentenced to death.
More information on John Dundas and his wife Helen Brown can be found in our book which documents not only Grace’s life but those of her extended family as well.
