Background
Born at Redbraes Castle, Berwickshire, Grizel Hume was the eldest daughter of Sir Patrick Hume, Bt (later Earl of Marchmont). When she was twelve years old, she carried letters from her father to a Scottish conspirator in the Rye House Plot, Robert Baillie of Jerviswood, who was then in prison. In 1692, Lady Grizel married George Baillie, son of Robert.
Career
Hume"s sympathy for Baillie made him a suspected man, and the king"s troops occupied Redbraes Castle. They returned to Scotland after the Glorious Revolution. The couple had first met when they were twelve, and supposedly fell in love at that point.
They also had a short-lived son, Robert (23 February 1694 – 28 February 1696).
Grizel died in London on 6 December 1746, and was buried at Mellerstain on 25 December, her eighty-first birthday. Although not intended for publication, the biography appeared in print in 1809 in Observations on the Historical Work of the Right Honorable Charles James Fox under the title "Lady Murray"s Narrative".
George Baillie"s Correspondence (1702-1708) was edited by Lord Minto for the Bannatyne Club in 1842. Lady Grizel was also memorialized by Scottish poet Joanna Baillie, who claimed to be a distant relative, in a poem first published in 1821 in Metrical Legends of Exalted Characters.
