William Francis Spencer Ponsonby, 1st Baron de Mauley (31 July 1787 – 16 May 1855) was an English Whig and Liberal politician who sat in the House of Commons between 1826 and 1837. He was raised to the Peerage in 1838.

Life[edit]

Ponsonby was the youngest child of 3rd Earl of Bessborough and his wife Henrietta Ponsonby, Countess of Bessborough.[1]

Ponsonby was elected Member of Parliament for Poole in 1826 and held the seat until 1831.[2] He was then MP for Knaresborough between June and December 1832.[3] At the 1832 UK general election he was elected MP for Dorset and held the seat until 1837.[4] In 1838 he was created Baron de Mauley.

When the marriage of his sister Lady Caroline Lamb to William Lamb, 2nd Viscount Melbourne began to break up, he strongly supported Caroline.[5] Unfortunately he was not noted for tact or intelligence- William's devoted sister Emily Lamb, Lady Cowper described him as universally regarded as " an ass and a jackanapes".[6] He reminded Melbourne that the Lamb family were socially parvenu and that his sister had married beneath her; although true, these remarks were so tactless that Melbourne broke off any further dealings with him.[7]

Family[edit]

On 8 August 1814, Ponsonby married Lady Barbara Ashley-Cooper (the only daughter and heir of the 5th Earl of Shaftesbury and a co-heir of the medieval Barony of Mauley). They had three children:[1]
