Mary Catherine Bolton

Mary Catherine Bolton, later known by her married name of Lady Thurlow (1790/91—1830) was a notable English actress, remembered particularly for playing Ophelia.

Bolton was the daughter of James Richard Bolton, an attorney. She made her first appearance on the stage on 6 October 1806, in The Beggar's Opera.

In 1811, she played the part of Ophelia in Hamlet opposite John Kemble, giving a performance described as "in a decorous style, relying on the familiar images of the white dress, loose hair, and wild flowers, to convey a polite feminine distraction".

On 13 November 1813, at St Martin's-in-the-Fields, she married Edward Hovell-Thurlow, 2nd Baron Thurlow (1781—1829), and her stage career ended. They had three sons, including Edward Thomas Hovell Hovel-Thurlow, the fourth baron. At the time, it would not have been socially possible for a woman who had married into the ruling class to continue a career as an actress.

Her descendant Roualeyn Hovell-Thurlow-Cumming-Bruce, 9th Baron Thurlow, inherited the title in 2013 and in 2015 was elected by his fellow peers to a vacant seat in the House of Lords.
