Margaret Wemyss, 3rd Countess of Wemyss and Countess of Cromarty (1 January 1659 – 11 March 1705) was a Scottish peer.[1][2]
Margaret was the daughter of David Wemyss, 2nd Earl of Wemyss and Margaret Leslie, daughter of John Leslie, 6th Earl of Rothes. She was the youngest of sixteen children; she and her older sister, Lady Jean Wemyss (a half-sister by her father's first wife), were the only ones who did not die young and childless.[1] Normally the family's titles would have gone to the older daughter but "owing to special circumstance", Margaret was preferred over Jean. Jean Wemyss disputed this and the case was discussed before the Scottish Parliament, where Margaret prevailed. She succeeded to the family title in 1679.
On 28 March 1672 at age 13, Margaret married her cousin, Sir James Weymss of Caskieberry (later created Lord Burntisland for life) and they had three surviving children:
After Lord Burntisland died in 1682, the Countess married Sir George Mackenzie of Tarbat (later created Earl of Cromartie).
