Lady Anne Smith, the Duke of Wellington's sister. (This marriage, in contravention of the canon laws of the Church of England, rendered his marriage potentially annullable for many years: for this reason, Wellington himself strongly opposed it.) They had seven children, one son and six daughters: •

22 Arlington Street in
St. James's, a district of the
City of Westminster in central London from
John Pratt, 1st Marquess Camden and proceeded to expend enormous sums refurbishing the interior of the house. He renamed the house after his title and during his residency, it was known as "Beaufort House." He hired architect
Owen Jones, who had studied the
Alhambra to embellish the interiors. Beaufort sold the house a year before he died to
William Hamilton, 11th Duke of Hamilton. Beaufort died in 1853, aged 61 at
Badminton House,
Gloucestershire, and was buried at
St Michael and All Angels Church, Badminton. He is best known today for his two marriages, and his involvement, as a very young man, with the courtesan
Harriette Wilson, to whom he apparently proposed marriage. ==Fictional portrayal==
