Leke was created a
baronet in 1611, and in 1624 was raised to the
peerage as
Baron Deincourt (or d'Eyncourt) of Sutton.
Robert Thoroton supposed a d'Eyncourt connection through Morton and
Parkhall in
Derbyshire, once belonging to the d'Eyncourts, later to the Leke family. In 1629, Baron Deincourt was the subject of legal action by his widowed mother over non-payment of monies owed to his dead father. In the
Civil War, st the beginning of April 1643, Deincourt began to fortify his house at
Sutton.
Sir John Gell, 1st Baronet sent his brother Colonel Thomas Gell, with 500 men and three pieces of ordnance, to besiege it. Deincourt was summoned, but refused to surrender, and for some time obstinately defended himself. The house was taken, and Deincourt and his men were made prisoners; the works were demolished, and Deincourt was set at liberty, on giving his word that he would go to Derby within eight days and submit himself to the Parliament. Sir John Gell observes, that the forfeiture of his word, on this occasion, was revenged by the garrison at Bolsover, who some time afterwards, when that castle was in the hands of the Parliament, plundered Deincourt's house at Sutton. In the same year, fighting under Lord Deincourt's banner, two of his sons were killed fighting for the king at the
Battle of Lansdowne, on 5 July 1643. In 1645 Lord Deincourt was created
Earl of Scarsdale. Unpopular with Parliament as a royalist, his estates were sequestered; and as he refused to accept a fine from the
Committee for Compounding with Delinquents, they were sold. His son found some friends to be the purchasers, and he paid the sum of £18,000, fixed by the Parliamentary commissioners as the composition. ==Death and burial==
