Elizabeth Barbara Bulwer-Lytton (née Warburton-Lytton; 1 May 1770[1] – 19 December 1843)[2][3] was a member of the Lytton family of Knebworth House in Hertfordshire, England.
In 1798, she married General William Earle Bulwer (1757–1807), and the couple lived at Heydon Hall in Norfolk.
She renovated it by demolishing three of its four sides and adding Gothic towers and battlements to the remaining building.
Because of a long-standing dispute she had with the church, she is buried not with her ancestors at St Mary's Knebworth, but in the Lytton Mausoleum nearby which she commissioned from John Buonarotti Papworth in 1817.
Elizabeth's death greatly affected her son, as described in a letter originally published in 1845, and again in a posthumous 1875 collection.
