Jane Heathcote-Drummond-Willoughby, 28th Baroness Willoughby de Eresby

Nancy Jane Marie Heathcote-Drummond-Willoughby, 28th Baroness Willoughby de Eresby (; born 1 December 1934) is an English peer. She is a holder of the office of Lord Great Chamberlain, which is currently exercised by the 7th Marquess of Cholmondeley.
Family.
She is the daughter of James Heathcote-Drummond-Willoughby, 3rd Earl of Ancaster, and the Hon. Nancy Phyllis Louise Astor (daughter of Waldorf Astor, 2nd Viscount Astor). Her brother Timothy Gilbert (born 19 March 1936), heir apparent of the Earldom of Ancaster, was lost at sea in 1963.
Adult life.
Lady Willoughby was one of the six Maids of Honour at the 1953 coronation of Queen Elizabeth II. 
Her father was the third and last Earl of Ancaster. On his death in 1983, the earldom became extinct, but according to the rules of succession to the ancient peerage, she succeeded him as Baroness Willoughby de Eresby. She became the sixth woman to hold the barony, which is distinguished by its suffix from that of Willoughby de Broke. She also inherited divided between Lincolnshire and Perthshire and in 2008 was ranked 1572nd in a list of richest people forming the "annual report of the Sunday Times", citing her wealth as £48 million. The annual report includes domiciled and non-domiciled visitors believed to be in the United Kingdom at the start of each year. Her father left net assets subjected to tax to his heirs on his death attested as £1,486,694 (), but may have transferred assets before his death. 
In 1987, Lady Willoughby became a patron of King Edward VI School in Spilsby (now King Edward VI Academy). She also served as a Deputy Lieutenant of Lincolnshire.
Like most other hereditary peers, Lady Willoughby lost her seat in the House of Lords as a result of the House of Lords Act 1999. She has not been elected as one of the ninety hereditary peers to hold a seat for life. However, she has a quarter-share in the hereditary position of Lord Great Chamberlain, which carries with it a seat in the House of Lords, although the quarter share means only that she is a "Joint Hereditary Lord Great Chamberlain", with the possibility of gaining the position in every fourth monarch's reign; her relevant family tree back to 1789 features in this regard, as the office was split by decision of the House of Lords between the daughters of Robert Bertie, 4th Duke of Ancaster and Kesteven (who was also Lord Willoughby de Eresby and Marquess of Lindsey). 
Lady Willoughby de Eresby is unmarried and without issue. This leaves co-heirs presumptive of the peerage Sebastian St Maur Miller (b. 1965), her older aunt's grandson, and Sir John Aird, 4th Baronet (b. 1940), her younger aunt's son. They will share in the Lord Great Chamberlain's quarter-interest, leaving them one eighth of the role each, ranking them second behind the Marquess of Cholmondeley, who takes the role in every alternate reign.
