Early life
Erskine was born in 1670 near Montrose, in Angus. He was the third, but second surviving, son of David Erskine of Dun (1640–1698) and Margert (née Lumsden) Ramsay. His mother, a daughter of Sir James Lumsden of Innergellie, was a widow of Thomas Ramsay of Bamff, Perthshire. His father succeeded his elder brother, Sir Alexander Erskine, as the Laird of Dun. His elder brother was James Erskine, an MP for Aberdeen Burghs, whom his father disinherited in favour of David. His younger brother was Alexander Erskine, of Balhall (whose descendants became heir male of Erskine of Dun following the death of Lord Dun's great-grandson, William John Erskine, in 1798).
He studied at the universities of St. Andrews and Paris.
Career
Erskine became a member of the Faculty of Advocates on 19 November 1698, and soon rose to eminence. He represented Forfarshire at the convention of estates, 1689, and in the Parliaments of 1690, 1691, 1693, 1695, and 1696, and opposed the union.
