Johnston/e’s were a Border clan which held the central lands of Annandale. The name Gilbert Johnstone is found in records after 1194. The Johnstones became involved in the conflict between the Royal House of Stewart and the House of Douglas and for their loyalty were rewarded with confiscated lands near the Douglas stronghold of Threave Castle in Galloway.
Annandale - In 1633, James Johnstone was created Lord Johnstone of Lochwood by Charles I. In 1643, he was created Earl of Hartfell and aligned himself with the Royalist Cause. He was captured and imprisoned, but after the Restoration was given the additional earldom of Annandale.
In 1701, William, 3rd Earl of Hartfell and 2nd Earl of Annandale, Secretary of State for Scotland and President of the Privy Council, was created 1st Marquess of Annandale. He was succeeded by his two sons, but after the death of the 3rd Marquess the family titles became dormant and the Johnstone estates descended via the female line to the Hopetoun Family. In 1985, based on the Charter of 1662, the Johnstone Chiefship and the earldoms of Annandale and Hartfell were confirmed upon Patrick Johnstone of that Ilk.
Caskieben - Sir George Johnston of Caskieben, who claimed descent from Stiven de Johnston in the 14th century, was created a Baronet of Nova Scotia in 1626. Arthur Johnston (1587-1641), son of the Laird of Caskieben, became Rector of King's College, Aberdeen.
