Harriet Cholmondeley (c.1790 –[1] 11 July 1815), sometimes called "Lady" or "The Hon" Harriet Cholmondeley, was the first wife of John Lambton, 1st Earl of Durham.
A portrait of her as a child, by John Hoppner, is held by the Tate Gallery.
[3] Lambton, who at the time was a commoner, an army officer and the son of an MP, was under 21 and was refused permission to marry by his guardians.
[5] The couple eloped to Scotland and married at Gretna Green on 1 January 1812; they subsequently went through an Anglican wedding ceremony on Harriet's father's estate at Malpas, Cheshire, on 28 January.
They had three daughters, all of whom died as young women: Harriet died, probably of tuberculosis,[4] a few weeks after the birth of her youngest daughter.
