Hay baronets

There have been four baronetcies created for persons with the surname Hay, all in the Baronetage of Nova Scotia. Two creations are extinct, one dormant and one 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 16000 acre 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.

The Hay Baronetcy, of Linplum in the County of Haddington, was created in the Baronetage of Nova Scotia on 26 March 1667 for James Hay, son of the Hon. William Hay, who was son of the 8th Lord Hay of Yester and brother of the 1st Earl of Tweeddale. The title became extinct on the death of the second Baronet in 1751.

The Hay Baronetcy, of Alderston, was created in the Baronetage of Nova Scotia on 22 February 1703 for John Hay, with remainder to heirs male forever. He was a member of the same family as the Hay Baronets of Smithfield and Haystoun and the Marquesses of Tweeddale. The third and fourth Baronets used the surname of Hay-Makdougall. The ninth Baronet never proved his succession or used the title. Two other members of the family may also be mentioned. Thomas Hay, grandfather of the fifth Baronet, was a Lord of Session under the judicial title of Lord Huntingdon. The younger brother of Thomas Hay, John Hay of Restalrig, joined Prince Charles Edward Stuart in the Jacobite rising of 1745. He was by "King Charles III" created a knight and baronet of Nova Scotia in the Jacobite Peerage with remainder to heirs male; this title merged with the 1703 creation in 1825. Woulfe Hay, grandson of Captain John Hay, half-brother of the fifth Baronet, was a Major-General in the British Army.
