Henry Seymour, 9th Marquess of Hertford

Henry Jocelyn Seymour, 9th Marquess of Hertford, (born 6 July 1958) is a British peer, the son of Hugh Seymour, 8th Marquess of Hertford. He was educated at Harrow School and the Royal Agricultural College, Cirencester. He currently resides at Ragley Hall, Warwickshire, where he has been in charge of the estate since 1991.

He was a member of the House of Lords from 1997 to 1999 and is a Deputy Lieutenant of Warwickshire.

Family life In 1990, he married Brazilian-born Beatriz Karam. They have four children:

(b. 23 April 1992) , Earl of Yarmouth (b. 2 November 1993). He is married to Kelsey Wells and they have two sons: Clement Andrew, Viscount Beauchamp (b. 29 November 2019) and The Honourable Jocelyn William (b. 25 August 2021) (b. 24 January 1995) (b. 24 July 1998)

The Marquess and Marchioness were taken to court by their elder son and heir William Seymour over his claim that he expected to take over Ragley Hall when he turned 30. His relationship with his parents had "deteriorated very sharply" following his marriage in 2018. William also had questioned his father's mental capacity during court hearings in February 2025, but the court ruled in favor of the Marquess who argued that his son's "lack of achievement" and failure to graduate university would render him unsuitable for managing the estate.
