The Tichborne Baronetcy, of Tichborne in the County of Hampshire, was created in the Baronetage of England on 8 March 1621 for Sir Benjamin Tichborne, who was a Member of Parliament (MP) for Petersfield from 1588 to 1589 and for Hampshire in 1593.
The inheritance of the titles has been complicated, coming through two sons of Sir Benjamin, 1st Bt, Richard and Walter.
Sir Richard, 2nd Bt, eldest son of 1st BT. He married Susan Waller and was succeeded by his son Sir Henry, 3rd Bt who married Mary Arundell. He was succeeded by his son Sir Henry 4th Bt, who married Mary Kemp. The 4th Bt had only daughters so was succeeded by his brother Sir John, 5th Bt, a Jesuit priest. One daughter of Sir Henry (4th Bt), Mary Agnes married Michael Blount of Mapledurham.
The baronetcy then reverted to descendants of Sir Benjamin's second son, Sir Walter Tichborne, Kt, of Aldershot. Sir Walter married Mary White, by her inheriting land in Aldershot (the family had a home in Aldershot Park for many years before building a grander home at Manor Park where they lived for nearly 200 years). His son Francis Tichborne married Susanna Hawes and their son White Tichborne, an MP, married, secondly, Anne Supple. White's son James Tichborne married Mary Rudyard (or Rudyerd) and their son Henry became the 6th Bt and married his fourth cousin, Mary Blount, daughter of Michael Blount and Mary Agnes Tichborne. Thus later baronets are genealogically descended from both lines.
Sir Henry's son, Sir Henry, 7th Bt, married Elizabeth Plowden and they had seven sons. Their eldest son Sir Henry, 8th Bt, married Anne Burke and they had seven daughters and no sons. The 8th Bt was succeeded by his brother Edward, who had taken the name Doughty and on becoming 9th Bt assumed the name, Sir Edward Tichborne-Doughty. He married Katherine Arundell and his son died as a child, so he was succeeded by his brother Sir James Tichborne, 10th Bt, who married Henriette Felicite Seymour.
Following the disappearance in 1854 of Roger Charles Tichborne, the heir to title of the 10th Baronet, the appearance in 1866 of a claimant led to a highly-publicised legal battle known as the Tichborne Case, at the end of which the claimant was declared an impostor. In 1866, the wealth of the 11th Baronet included Tichborne Park's 2,290 acres (930 ha), manors, lands and farms in Hampshire, and considerable properties in London and elsewhere, which altogether produced an annual income of over £20,000, equivalent to several millions in 21st-century terms.
