Sackville Pelham, 5th Earl of Yarborough

Sackville George Pelham, 5th Earl of Yarborough, MC (17 December 1888 – 7 February 1948), styled Lord Worsley from 1914 to 1926 and known as The Lord Conyers from 1926 until his accession to the earldom in 1936, was a British peer and soldier.

Pelham was the second son of Charles Pelham, 4th Earl of Yarborough and his wife, Marcia. In 1910, he became a Second Lieutenant in the 11th Hussars and initially fought as a lieutenant in France during World War I before being promoted to the rank of captain in 1916. During the war, his elder brother, Charles was killed in action and Sackville assumed the former's courtesy title of Lord Worsley. After the war, he was awarded the Military Cross and retired from the Army in 1919 when he married Nancye Brocklehurst (a niece of Lord Ranksborough). The couple later had two daughters, Diana Mary (b. 1920) and (June) Wendy (1924-2012).

In 1926, Lord Worsley became a major in the Nottinghamshire Yeomanry and on the death of his mother that year, inherited the baronies of Conyers and Fauconberg and the Portuguese countship of Mértola. He later inherited the earldom of Yarborough from his father in 1936.

From 1936-40, Lord Yarborough commanded the Nottinghamshire Yeomanry as a Lieutenant Colonel and fought in World War II from 1939-44. On his death in 1948, the earldom passed to his brother, Marcus, whilst the countship passed to his eldest daughter, Lady Diana, and the baronies went into abeyance between his two daughters. The death of his youngest daughter in 2012 terminated the abeyance in favour of Diana, who succeeded him in the baronies at that point.
