Thomas Dalmahoy (died 1682) was an English politician as the (co-)Member of Parliament for Guildford, 1664-1679. His left-handed marriage is notable in that he married the widow of his family's patron, killed at the final foray of the English Civil War, the Battle of Worcester, having served as his master of the horse attending to his travel arrangements — the patron was the Duke of Hamilton. In his final years, being a noble Scotsman, among a minority of all members supportive of Lauderdale in the Cabal and the succession of James II and VII — considered one of the Court Party and not holding a Pocket Borough — he lost the 1679 election to exclusionist Morgan Randyll. Marriages In the last 20 years of his life he owned and lived at "The Friary", Guildford and Wanborough Manor, Surrey, having inherited from his first wife Lady Elizabeth Maxwell (died 1659), widow of William Hamilton, 2nd Duke of Hamilton and the co-heir of her father, James Maxwell, 1st Earl of Dirletoun; the year before he died he married Elizabeth Clerke, widow of Sir William Clerke, 2nd Baronet. Career He was a Member (MP) of the Parliament of England for Guildford, elected twice after the English restoration of the monarchy: in 5 December 1664 and March 1667. Biography Dalmahoy came from a 13th century Scottish knightly family and was third son of Sir John Dalmahoy of Dalmahoy, Ratho, Midlothian. As his family were long supporters of the family, he became master of the horse to William Hamilton, 2nd Duke of Hamilton, who was mortally wounded in 1651 at Worcester in the Royalist cause — Dalmahoy arranged his funeral, and later married his widow, Elizabeth Maxwell, a daughter of the Earl of Dirletoun. In the interregnum lasting until 1680 Hamilton estates in Scotland were sequestrated; but as a half-share of his father-in-law's estate through his wife Elizabeth devolved to him, the Friary, Guildford and Wanborough Manor became his. Her noble daughters apparently disputed some part of the settlement. Samuel Pepys, meeting the "Scotch gentleman" on his way to the exiled Court in May 1660, found him "a very fine man", and Speaker Onslow, who was young kin to Dalmahoy’s second wife born at East Horsley, called him "genteel and generous". He was proposed for the order of the Royal Oak, with a (government-funded) annual income of £1,200 (). Dalmahoy was elected for Guildford at
