Colonel William Bosville, FRS, of New Hall, Gunthwaite, of Thorpe Hall, Rudston, both in Yorkshire, and of 76 Welbeck Street, St Giles in the Fields, London, was an English landowner and celebrated bon vivant. In politics he was an ardent Whig. When his friend William Cobbett was in Newgate Prison, Bosville went in his coach and four to visit him, and afterwards gave him a cheque for £1,000 as a token of sympathy with him in his persecutions. In appearance he was almost as eccentric as in his manners. He used always to dress in the style of a courtier of King George II, and wore a single-breasted coat, powdered hair and queue. In 1792 he was elected a Fellow of the Royal Society of London. He appears as a minor figure in several political caricatures by James Gillray and two portraits of him survived at Thorpe Hall in 1927.
After being educated at Harrow School, he obtained a commission in the Coldstream Guards on 24 December 1761. He was raised to the rank of lieutenant on 11 January 1769, and served with his regiment through part of the American War of Independence, where "no doubt he imbibed his republican sentiments". He retired from the army in June 1777. Upon his return from America he travelled in France, Italy, and Morocco. Though he never attained any higher rank in the guards than that of lieutenant, he was generally known as Colonel Bosville.
Residence
After he had settled down in England he hardly ever left London for more than a day, as he used to say that it was the best residence in winter and that he knew no place like it in summer. His house was number 76 Welbeck Street, Westminster. Once when in Yorkshire, it is said that he made a point of not visiting his property, which was of considerable extent, "lest he should be involved in the troubles of a landed proprietor".
Social life
He was an intimate friend of John Horne Tooke, to whose house at Wimbledon Bosville used to drive down in a coach and four to dinner every Sunday during the spring and autumn for many years, and is mentioned in his Diversions of Purley. Possessed of a large fortune he was exceedingly generous with his money, and was unbounded in his hospitality. Every weekday he used to receive some of his friends at dinner at his house in Welbeck Street. The party never exceeded twelve in number, and the dinner hour was always five o’clock punctually. A slate was kept in the hall, in which any of his intimate friends might write his name as a guest for the day, Besides Horne Tooke, Sir Francis Burdett, 5th Baronet, Lords Hutchinson and Oxford, Parson Este, and others, often availed themselves of this privilege. The first stroke of five was the signal for going downstairs, and the host made a point of never waiting for any of his guests. In accordance with his favourite maxim, namely Some say better late than never; I say better never than late, an old friend who arrived one day four minutes late was refused admittance by the servant, who said that his master was "busy dining". Though his health declined and his convivial powers failed, he still continued his dinner parties to the last. Even when compelled to remain in his bedroom, the slate was hung in the hall as usual, and on the very morning of his death he gave his orders for the dinner at the usual hour.
Death and burial
He died unmarried at his house in Welbeck Street on 10 December 1813 in his sixty-ninth year, and was buried on the 21st of the same month in the chancel of St Giles in the Fields.
Heir
By his will left nearly the whole of his fortune and estates to his younger nephew Col. Hon. Godfrey Macdonald , who in 1814 in accordance with the will, by royal licence changed his surname to Bosville. He was the second son of William's sister Elizabeth Diana Bosville and her husband Sir Alexander Macdonald and therefore had no expectation of a paternal inheritance. However, his elder brother Alexander Macdonald, 2nd Baron Macdonald died unmarried in 1824, when Godfrey became heir to the title and to the Macdonald estates.
