barony in the Peerage of the United Kingdom

Baron de Mauley, of Canford in the County of Dorset, is a title in the Peerage of the United Kingdom. It was created on 23 June 1838 for the Whig politician the Hon. William Ponsonby, who had earlier represented Poole, Knaresborough and Dorset in the House of Commons.
History
The 1st Baron de Mauley was the third son of the 3rd Earl of Bessborough, an Anglo-Irish peer, and his wife Lady Henrietta Spencer, daughter of the 1st Earl Spencer. He married Lady Barbara Ashley-Cooper, the daughter of Anthony Ashley-Cooper, 5th Earl of Shaftesbury. She was one of the co-heirs to the ancient barony by writ of Mauley (or Maulay), which superseded the feudal barony the caput of which was at Mulgrave Castle, Yorkshire, which barony by writ had become extinct in 1415.
Their son, later the 2nd Baron, sat as Member of Parliament for Poole and Dungarvon. He married his first cousin Lady Maria Ponsonby, daughter of the 4th Earl of Bessborough.
Their eldest son, the 3rd Baron, never married, so the barony was inherited by his brother, who became the 4th Baron. He married the Hon.
