“ When Richard died unmarried in Paris in August 1870 his title passed to his kinsman, Francis Hugh George Seymour (1812–1884) , a descendant of the 1st marquess, whose son, Hugh de Grey (b. 1843) became 6th marquess in 1884. The 4th marquess left his great wealth and his priceless collection of art treasures to Sir Richard Wallace (1818–1890) , his reputed half-brother, and Wallace’s widow, who died in 1897, bequeathed the collection to the British nation. It is now in Hertford House, formerly the London residence of the marquesses of Hertford. ”

“ His son, Francis Ingram Seymour Conway (1743–1822) , who was known during his father’s lifetime as Lord Beauchamp, took a prominent part in the debates of the House of Commons from 1766 until he succeeded to the marquessate in 1794. ”
