coat of arms

Sir George Douglas of Mordington has been identified as the brother of James Douglas, Lord Torthorwald, (d Jul 1608) but may have been of an earlier generation, making him a grandson of James, 4th earl of Morton. He married, as her 3rd husband, Margaret Dundas, dau of Alexander Dundas of Fingask, who died at the battle of Pinkie.

The feudal barony of Mordington was long held by the Douglas of Dalkeith family but was split, with Crown consent, early in the 17th century. At that time Over Mordington came into the ownership of Sir James Douglas (died 1656), a son of William Douglas, 10th Earl of Angus. In 1641 Sir James Douglas was made a Lord of Parliament as Lord Mordington.

The descendants of James Douglas, 1st Lord Mordington, never adopted the surname Oliphant, despite his marriage to Ann Oliphant, heiress of the last Lord Oliphant. Their connection to the Oliphant line created a complex legal dispute over the peerage, and although the Court of Session confirmed that the old Oliphant title could descend through an heiress, it also ruled that the dignity had been resigned and therefore reverted to the Crown. King Charles I subsequently granted the collateral male Oliphant heir a new creation of the title “Lord Oliphant,” while awarding James Douglas and his wife the precedency of the ancient Oliphant peerage under a different designation: Lord and Lady Mordington. From that point onward, the family held the Mordington title and consistently retained the surname Douglas, with successive holders — William, James, and Charles Douglas — appearing in all peerage records under that name. The association with the Oliphants was therefore one of marital inheritance and ceremonial precedence, not a change of identity, and no branch of the Douglas‑Mordington line is known to have adopted the Oliphant surname.
