The special remainder to the Earldom of Ilchester created in 1756
From the London Gazette of 12 June 1756 (issue 9591, page 2):-
The King has been pleased to grant unto the Right Honourable Stephen Lord Ilchester and Stavordale, Baron of Woodsford Strangways in the County of Dorset, and of Redlynch in the County of Somerset, and his Heirs Male, and in Default of such Issue, to his Brother the Right Honourable Henry Fox, and his Heirs Male, the Dignity of an Earl of the Kingdom of Great Britain, by the Name, Stile and Title of Earl of Ilchester in the County of Somerset.
Henry Thomas Fox-Strangways, 2nd Earl of Ilchester
According to a romantic tale, in the early 1770s the 1st Earl of Ilchester received a letter from a gentleman named Standish O'Grady who lived with his daughter at Cappercullin, county Limerick in Ireland. The letter respectfully requested that the Earl arrange for his son and heir, Henry Thomas Fox-Strangways, known by the courtesy title of Lord Stavordale, and whose regiment (the 24th Regiment of Foot) was stationed near to O'Grady's house, to be transferred to another part of the country.
Mr. O'Grady stated in his letter that Lord Stavordale was paying a great deal of attention to his daughter, and expressed his concerns that, because Lord Stavordale was a member of the aristocracy and his daughter was a mere commoner, they would never be allowed to marry, and that, as a result, his daughter's happiness would suffer if the hopeless love affair was allowed to progress any further.
In reply, Lord Ilchester wrote that he was very grateful for the timely warning of the state of affairs, and that he had requested an old friend of his, named Colonel Prendergast, to call upon Mr. O'Grady to personally convey his thanks. When Colonel Prendergast arrived, he and O'Grady got on so well that the Colonel was asked to stay for a week, during which period the Colonel spent a large amount of time with O'Grady's daughter.
At the end of the week, when the time came to leave, the Colonel told O'Grady that his daughter did not appear to be well, to which O'Grady replied that she was still pining for Lord Stavordale. The Colonel then informed O'Grady that he was totally confident that Lord Ilchester would be proud to have O'Grady's daughter as his daughter-in-law, and that he would tell him so. O'Grady begged the Colonel to say nothing to the Earl, but the Colonel insisted that the Earl would be pleased to welcome the daughter into his family. Finally, when O'Grady asked why he was so confident, the Colonel replied, "Because I am Lord Ilchester".
Lord Stavordale and Mary Theresa O'Grady were married on 26 August 1772. The marriage produced two sons and six daughters. When the 1st Earl of Ilchester died in 1776, and was succeeded by his son, Mary O'Grady became the Countess of Ilchester until her death on 14 June 1790.
Richard Martin Herbert Peake (7 Aug 1953‑19 Jul 1975), son and heir of the 2nd Viscount Ingleby
Peake fell to his death from a cliff in July 1975. The following report of the subsequent inquest appeared in The Times of 25 July 1975:-
A coroner recorded an open verdict yesterday on Mr. Richard Peake, aged 21, son of Lord Ingleby, who fell to his death at Beachy Head, Sussex.
Mr. John Dodd, the East Sussex coroner, said: "I must be satisfied beyond all reasonable doubt when a person's life ends in this way before I bring in a verdict of suicide". He said it was probable Mr. Peake had not realised that he was so near the edge of the cliffs.
Mr. Anthony Watkins, aged 26, a friend, said he clung to Mr. Peake to try to prevent him from falling over the edge. "He then grabbed my wrist and said 'OK, chum, you are coming with me'. I held for an instant and then I let go." Mr. Watkins said Mr. Peake slid about a foot and then went straight down.
In reply to a question from the coroner, he said: "No, there is no question of a leap".
Mr. Watkins told the coroner earlier that the Wednesday before Mr. Peake's death he had brought his friend away from Poole General Hospital, Dorset, after he had tried to cut his wrist and throat. He also said Mr. Peake had spoken of past suicide attempts.
As a result of this death, the Viscountcy of Ingleby became extinct on the death of the 2nd Viscount.
