Family
Lord Westminster married Lady Elizabeth Leveson-Gower, younger daughter of George Leveson-Gower, 2nd Marquess of Stafford (later 1st Duke of Sutherland), in 1819. Following their marriage, Westminster and his wife initially lived at Eaton Hall, Cheshire, the family's country house, with Lord and Lady Grosvenor. During the London season, from April each year, the family lived in Grosvenor House. In 1827 the couple visited Norway, Sweden and Russia and in 1835–36 they toured through Germany and Italy. When the 1st Marquess died in 1845 they followed the family tradition of using Eaton Hall as their country house and Grosvenor House as their London residence, where they entertained lavishly.
Lord Westminster and his wife had thirteen children, ten of whom survived into adulthood and three of whom lived into their nineties. Their second son Hugh Lupus Grosvenor succeeded him as 3rd Marquess; he was later created Duke of Westminster. Their youngest son Lord Richard Grosvenor was ennobled as Baron Stalbridge.
