Henry Dawnay, 3rd Viscount Downe
Lieutenant-Colonel Henry Pleydell Dawnay, 3rd Viscount Downe FRS (8 April 1727 – 9 December 1760), was a British soldier and politician.
Dawnay was the eldest son of the Honourable John Dawnay, son of Henry Dawnay, 2nd Viscount Downe.
His mother was Charlotte Louisa, daughter of Robert Pleydell, of Ampney Crucis, Gloucestershire.
He succeeded his grandfather in the viscountcy in May 1741, aged 14.
As this was an Irish peerage it did not entitle him to a seat in the English House of Lords (although it did entitle him to a seat in the Irish House of Lords).
He was consequently eligible for election to the House of Commons and in 1750 he was returned as one of two Knights of the Shire for Yorkshire, a seat he held until his death ten years later.
Lord Downe also served in the Seven Years' War as a Lieutenant-Colonel in the 25th Foot.
He fought in the Battle of Minden in 1759 and commanded the regiment in the Battle of Campen in October 1760.

Educated at Eton, he became friends there with the son of Giles Earle( d. 1811).
He matriculated at Christ Church, Oxford in 1790, receiving his BA in 1795 and his MA in 1796.
In 1798, his brother John Dawnay, 5th Viscount Downe presented William to the rectories of Sessay and Thormanby.
Both of these livings are in North Yorkshire, and were in the patronage of the Dawnays, as was Ashwell, Rutland, to which he was presented by his brother in 1803.
On 6 June 1811, William married Lydia Heathcote daughter of John Heathcote of Connington Castle, by whom he had three children: Dawnay inherited Beningbrough Hall, Yorkshire, in 1827, upon the death of Margaret Earle, mother of his school friend at Eton.
Her sons predeceased her, and as she was the last of the Bourchier family that had owned Beningbrough, she left it to him.
He succeeded his brother as Viscount Downe in 1832.
Downe died at Torquay in 1846 and was succeeded by his eldest son William Henry.
Beningbrough, however, was left to Downe's second son, Payan.
