St Mawes from 1726 to 1727, and for Exeter from 1727 to 1728. He served as Secretary to the Prince of Wales from 1715 to 1727 and as Lord of the Admiralty from 1727 to 1728. Between 1727 and 1728 he represented Dublin University in the Irish House of Commons. Death and legacy Molyneux married Lady Elizabeth Capel, daughter of Algernon Capell, 2nd Earl of Essex, on 5 April 1717. In 1728, he suffered a fit while in the House of Commons. He was treated by court anatomist Nathaniel St André, but the treatment did not prove successful, and Molyneux died in Kew in April. On the night of the death, St André eloped with Molyneux's wife, Elizabeth, the two marrying in 1730. Samuel Madden, a relative of Molyneux's, claimed that St André had poisoned the MP. Although St André won an action for defamation, he found himself unable to secure regular work.
