Hay baronets
There have been four baronetcies created for persons with the surname Hay, all in the Baronetage of Nova Scotia. One creation is extinct, one dormant and two extant. A fifth baronetcy in the Jacobite Peerage, although theoretically extant, is not recognised by the Lyon Office.
The Hay Baronetcy, of Smithfield and Haystoun in the County of Peebles, was created in the Baronetage of Nova Scotia on 20 July 1635 for James Hay, Esquire of the Body to King James VI, with remainder to his heirs male whatsoever. Along with the baronetcy he was granted 16,000 acres (65 km2) of land in Nova Scotia. The title became dormant on the death of the third Baronet in 1683. In 1762 James Hay claimed and assumed the baronetcy as the great-great-grandson John Hay, younger brother of the grandfather of the first Baronet. A jury assembled at Perth in 1805 decided his claim was valid and in 1806 he matriculated arms as a Baronet in the Lyon Office. The sixth Baronet sat as Member of Parliament for Peeblesshire. The seventh Baronet was Member of Parliament for Linlithgow Burghs. The title became dormant on the death of the eleventh Baronet in 1966. The presumed heir to the baronetcy is the Marquess of Tweeddale as a descendant of John Hay, 3rd Lord Hay of Yester, great-great-uncle of the first Baronet.
The Hay Baronetcy, of Park in the County of Wigtown, was created in the Baronetage of Nova Scotia on 25 August 1663 for Thomas Hay. The seventh Baronet married Sarah, daughter of John Cossins by his wife the Hon. Elizabeth Susannah, daughter of George Thicknesse, 19th Baron Audley. Consequently, his descendants are also in remainder to the barony of Audley.
