Lady Grizel (or Grisell) Hume was the eldest daughter of Sir Patrick Hume, Baronet, later earl of Marchmont. She began to write poems and songs in childhood. As a young woman, she refused the position of maid-of-honor at the court of Mary, Princess of Orange. Sir Patrick's political sympathies made him a suspected man, and he had to flee Scotland for Holland, where his family joined him. They were able to return following the Glorious Revolution of 1688. In 1692, after turning down a more advantageous match, Lady Grizel married George Baillie, son of the Scottish patriot Robert Baillie. Lady Grizel Baillie's household books, meticulously kept from 1692 to 1746, and consisting of more than 1,000 pages of entries, contain valuable information about life in Scotland in the 17th and 18th centuries. In 1911, the Scottish Historical Society published a scholarly edition of Lady Grizel's accounts, edited by Robert Scott-Moncrieff. Lady Grizel's Memoirs were published earlier in 1822. Some of her simple and sorrowful Scottish songs appeared in Allan Ramsay’s Tea Table Miscellany (1724). Lady Grizel and her husband commissioned the architects William and Robert Adam to design their home Mellerstain House, where she is buried.
