In March 1565, Mary Livingston married John Sempill of Beltrees, a son of Robert Sempill, 3rd Lord Sempill, who had been born in England. The leading preacher of the Scottish Reformation, John Knox, disapproved of Queen Mary's court, and included some remarks on the marriage in his History of the Reformation in Scotland. According to Knox, Sempill was called the "Dancer", and Livingston was known as "Lusty" and pregnant before their wedding. Knox disapproved of grants of lands made by Queen Mary to the couple in 1565 including the barony of Auchtermuchty, rather than given to hard-working administrators. The 19th-century writer Agnes Strickland researched the marriage, noting that it was delayed rather than "shame-hastened" as Knox suggested, and had been discussed in autumn 1564. The marriage was celebrated at Court during the Shrove-Tide feast on 5 March, called "Fasterins Eve" in Scotland, and there was a Masque, for which a painter was paid £12 for making props. The diplomat Thomas Randolph called it the "great marriage of this happie Englishman that shall marrie lustie Livingston." Randolph heard of a plan to invite the Earl of Bedford who was Governor of Berwick-upon-Tweed to the wedding because Sempill's mother was English. The Earl of Bedford had not previously visited Edinburgh. Queen Mary gave her a present of a bed made from scarlet and black velvet, with embroidered taffeta curtains and silk fringes. Gifts of beds were not uncommon at the Scottish court, in 1593 Anne of Denmark gave her Danish maiden Margaret Winstar a rich velvet and silk bed.
Furs and jewels
She retained some of Mary Queen of Scot's jewels and sent them with Robert Melville of Murdocairny to her at Bolton Castle. John Sempill was charged by Regent Lennox to return some of the queen's jewels and furs of "martrick" and sable in his wife's keeping, but refused and was imprisoned in Blackness Castle. This fur may have been a zibellino, several were recorded in Mary's inventories.
Family
Her children included:
Sir James Sempill, Scottish Ambassador to England from 1591-1600.
