Henry Howard, 7th Duke of Norfolk, (11 January 1655 – 2 April 1701) was an English nobleman, politician, and soldier. He was the son of Henry Howard, 6th Duke of Norfolk, and Lady Anne Somerset, daughter of Edward Somerset, 2nd Marquess of Worcester, and Elizabeth Dormer. He was summoned to the House of Lords in his own right as Baron Mowbray in 1678. His unhappy marriage was a subject of much gossip, and ended in divorce. Marriage, separation and divorce He married Mary Mordaunt, the only surviving daughter and heiress of the 2nd Earl of Peterborough and Penelope O'Brien. They separated in 1685. He divorced her for her adultery with Sir John Germain in 1700, after a previous attempt at divorce in 1692 had failed when the House of Lords threw out his private Divorce Bill. Although he succeeded in obtaining damages in an action for criminal conversation, the details were so sordid that he may well have regretted the step, especially since the jury reduced his claim for £100,000 damages to £66, for which they were severely reprimanded by the presiding judge. The Duke was evidently in no position to condemn his wife's moral conduct: even his own counsel called it frankly a case of the pot calling the kettle black. He died without children, and was succeeded by his nephew, Thomas Howard, 8th Duke of Norfolk. His former wife married secondly Sir John Germain, 1st Baronet, who had been her lover for many years. She died in 1705. He was rarely on good terms with his father, particularly after 1677 when his father married Jane Bickerton, his mistress of many years standing, an act which caused a violent family quarrel. Later life Like almost all the Howards of Norfolk he was a devout Roman Catholic; but during the anti-Catholic hysteria engendered by the Popish Plot he publicly conformed to the Church of England. There is little doubt that this was simply a device to save the family estates. The ploy seems to have succeeded; although his father was charged with recusancy in 1680, the charge was quickly dropped. While the senior Howard line survived unscathed, their cousin William Howard, 1st Viscount Stafford, was executed for his supposed part in the Plot in December 1680. Henry as a peer in his own right, Baron Mowbray, sat as one of the peers who tried him. It is a sign of
