title: John Dawnay, 4th Viscount Downe
text: # John Dawnay, 4th Viscount Downe
  
  John Dawnay, 4th Viscount Downe (9 April 1728 – 21 December 1780), was a British peer and Whig politician.
  
  ## Background
  
  Dawnay was the younger son of the Honourable John Dawnay, eldest son of Henry Dawnay, 2nd Viscount Downe. His mother was Charlotte Louisa, daughter of Robert Pleydell, while Henry Dawnay, 3rd Viscount Downe, was his elder brother.
  
  ## Political career
  
  Dawnay was returned to Parliament for Cirencester in 1754. In 1760 he succeeded in the viscountcy after the death of his elder brother in the Seven Years' War. However, as this was an Irish peerage it did not entitle him to a seat in the English House of Lords and consequently did not prevent him from remaining a member of the House of Commons. In 1768 he was returned for Malton, a seat he held until 1774.
  
  ## Family
  
  Lord Downe married Lora, daughter of William Burton, in 1763. They lived at Cowick Hall in Yorkshire and had at least seven children:
  
  * John Dawnay, 5th Viscount Downe (1764–1832)
  * William Henry Pleydell Dawnay, died young
  * Hon. Catherine Dawnay (23 August 1768 – 9 July 1821)

  * Hon. Marmaduke Dawnay (26 July 1777 – 1 October 1851), later (1824) Marmaduke Langley
  * Hon. Rev. Thomas Dawnay (30 May 1779 – 1 January 1850), rector of Ashwell
  
  Lord Downe died in December 1780, aged 62, and was succeeded by his eldest son, John. The Viscountess Downe died in April 1812.
