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.
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.[4] Harriet's father also forbade the marriage.[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:
Lady Frances Charlotte (16 October 1812 – 18 December 1835), who married the Hon. John Ponsonby (later 5th Earl of Bessborough), but died a few months later of consumption; they had no children.
The Hon. Georgiana Sarah Elizabeth (2 March 1814 – 3 January 1833), who died unmarried
The Hon. Harriet Caroline (30 May 1815 – 12 June 1832), who died unmarried
Harriet died, probably of tuberculosis,[4] a few weeks after the birth of her youngest daughter.
