The aforementioned Lady Sophia Charlotte, who succeeded her father as second Baroness Howe in 1799, married the Hon. Penn Curzon, Member of Parliament for Clitheroe. He was the only son of Assheton Curzon, second son of Sir Nathaniel Curzon, 4th Baronet, of Kedleston (ancestor of George Curzon, 1st Marquess Curzon of Kedleston, and the Barons and Viscounts Scarsdale; see Viscount Scarsdale for earlier history of the family). Assheton Curzon represented Clitheroe in the House of Commons for twenty-seven years. In 1794 he was raised to the Peerage of Great Britain as Baron Curzon, of Penn in the County of Buckingham, and in 1802 he was further honoured when he was made Viscount Curzon, of Penn in the County of Buckingham, in the Peerage of the United Kingdom. Lord Curzon was succeeded by his grandson, the second Viscount. He was the only son of Penn Curzon and Lady Howe. In 1821 he assumed by Royal licence the additional surname of Howe and the same year the earldom held by his maternal grandfather was revived when he was created Earl Howe in the Peerage of the United Kingdom. In 1835 he also succeeded his mother as third Baron Howe. He was succeeded by his eldest son, the second Earl. He sat as Conservative Member of Parliament for Leicestershire South.
