Frederick Thellusson, 5th Baron Rendlesham
Frederick William Brook Thellusson, 5th Baron Rendlesham (9 February 1840 – 9 November 1911), was a British Conservative politician. He was born in Florence, Italy, to Frederick Thellusson, 4th Baron Rendlesham, and his wife Elizabeth Charlotte, daughter of Sir George Prescott, 2nd Baronet, and former wife of General Sir James Duff. His mother died when he was less than one year old. In 1852, aged twelve, he succeeded in the barony on the death of his father. However, as this was an Irish peerage it did not entitle him to a seat in the House of  Lords. Educated in England at Eton and Oxford, he was reportedly a fine footballer at Eton and maintained a keen interest in other sports in later life, being on the National Hunt Committee as well as a member of the Jockey Club and the Royal Yacht Squadron. Failing eyesight in 1911 caused him to resign from long-held positions as chairman of the East Suffolk County Council and the Suffolk Quarter Sessions. He subsequently contracted blood-poisoning, leading to the amputation of his left hand in July 1911. Lord Rendlesham married Lady Egidia, daughter of Archibald Montgomerie, 13th Earl of  Eglinton, in 1861. They had three sons and five daughters. Lady Rendlesham died in January 1880. Lord Rendlesham remained a widower until his death in November 1911, aged 71. He was succeeded in the barony by his eldest son Frederick.
