In 1584, the lordship of Methven came to the then Duke of Lennox, in whose family it continued until it was purchased from the last Duke, in 1664, by Patrick Smythe of Braco. Click on the image of David Smythe adjacent for further lineage details.
Lord David Methven was the son of David Smythe of Methven, and was born in 1746. He studied law, and passed advocate in 1769. In possession of the family estates, to which he succeeded on the death of his father in 1764, he did not seek to obtain practice at the bar, but resided entirely in Perthshire, and took an active and influential part in everything that related to the local interests of that county. It was not until after the death of his first wife, in 1795, that he returned to Edinburgh, and betook himself to the law as a profession. He was shortly afterwards appointed Sheriff-Depute of Perthshire, which office he held until he was promoted to the bench on the death of Lord Gardenstone in 1763. He was appointed one of the Commissioners of Justiciary in the room of Lord Abercromby in 1796
As a judge Lord Methven is represented to have possessed extensive general knowledge and soundness of understanding. He resigned his appointment as a Justiciary Lord in 1804; and died on the 30th of January 1806. His death was remarkably sudden. He was taken ill while walking on the street, and expired in half an hour after having been carried home. His remains were interred in the Canongate churchyard; and the great attendance at his funeral testified the general esteem in which he had been held.
Lord Methven lived in St. Andrew Square. He was twice married; first to Elizabeth Murray, daughter of Sir Robert Murray of Hillhead, Bart., and sister to General Sir James Murray Pulteney, Bart.; secondly, to Euphemia Amelia Murray, daughter of Mungo Murray, Esq. of Lintrose. He had large families by both marriages, of whom there survived three sons, Robert Smythe, Esq. of Methven; William Smythe, Esq., (born 1803) advocate; and the Rev. Patrick M. Smythe, of Tanworth, in the county of Warwick; and two daughters, the eldest of whom was married to the Right Hon. David Boyle, Lord Justice-Clerk.
David Smythe (of Braco) married (1707) Catherine Cochrane who died 1772. Their son, David Smythe was born in 1711 and died in 1764. He married Mary Graham. Their son, Lord David Smythe was 18th in descent through his father from Edward I and 12th, through his mother, from Henry VII and the Princess Elizabeth of York , heiress of the House of Plantagenet. Amelia Euphemia Murray was 7th in a direct descent from Henry VII and Elizabeth of York.
