At the death of William, the 4th Earl, in 1761, the Earldom and Lordship became dormant, as no-one could prove a claim to them.

The 11th holder of the titles, Ethel Sydney Keith-Falconer, married John Baird, 1st Viscount Stonehaven.

At the death of Lord Stonehaven, the titles Viscount Stonehaven (created 1938), and Baron Stonehaven (created 1925), both in the Peerage of the United Kingdom, as well as the Baird of Urie Baronetcy, in the Baronetage of the United Kingdom, passed to the couple's son, James Ian.

The Countess of Kintore, who died the day after her one-hundredth birthday, was the longest-lived female holder of a British peerage;[1][unreliable source] upon inheriting his mother's titles, her son James Ian changed his surname from Baird to Keith.

He has a sister, Lady Iona Delia Mary Gaddis Keith (born 1978), who in 2008 married Mark Hopkins, younger son of Mrs Violet Hopkins, of Welwyn Garden City.
