Source-derived summary

Helena Anne Beatrix Wentworth Fitzwilliam, Lady Rees-Mogg (née de Chair; born 1977), is a British heiress and television personality. She is married to Sir Jacob Rees-Mogg, former Conservative Member of Parliament for North East Somerset and Secretary of State for Business, Energy and Industrial Strategy.

Early life and family

Rees-Mogg is the only daughter of Conservative MP Somerset de Chair and Lady Juliet Wentworth-Fitzwilliam, the only child and sole heiress of the very wealthy 8th Earl Fitzwilliam (d. 1948), who died in a small aircraft crash when she was aged 13. Also killed was his intended second wife, Kathleen Cavendish, Marchioness of Hartington, a daughter-in-law of the 10th Duke of Devonshire and a sister of U.S. President John F. Kennedy. The de Chair family, settled in England since the end of the seventeenth century, was of Huguenot descent and could trace their ancestry to Rene de la Chaire, whose grandson, Jean de la Chaire, was ennobled as a marquis in 1600 by Henry IV of France. They rose to gentry status through generations of clergy. Her half-brother was Lord Nicholas Hervey. She is the aunt of former Olympic athlete Lawrence Clarke and former Conservative MP Theo Clarke.

She grew up at her family's estate of Bourne Park near Canterbury, Kent.
