Seton was born early in 1673, probably at Edinburgh, and died there in 1744. He was the eldest son of Sir Alexander Seton, Lord Pitmedden, a notable Scottish advocate and judge. Nothing his known of him until he became MP for Aberdeen in the Scottish parliament, taking over the seat once held by his father, in 1702 and holding it until the Union. He became known as one of the ‘country Whig’ party, equally opposed to Catholicism and corruption at Court, and was in favour of limiting the Power of the monarchy. He incurred the displeasure of William III on several occasions, and was once briefly imprisoned. Despite this he held several official posts, including commissioner of the justiciary for the Highlands in 1702, commissioner for public accounts in 1703–4, and collector of bishops’ rents from from 1705–14.
