Emily Seymour, Marchioness of Hertford

She was the daughter of David William Murray, 3rd Earl of Mansfield, and his wife, the former Frederica Markham.[1]

She married the marquess in London on 9 May 1839, more than thirty years before he inherited the title from his cousin, Richard Seymour-Conway, 4th Marquess of Hertford, who died without direct heirs. The couple had ten children:

• Frederica Georgina Seymour (c. 1841–1848), who died in childhood
• Lady Horatia Elizabeth Seymour (1842–1922), who married Sir Henry David Erskine, a direct descendant of the Earls of Mar and had children
• Hugh de Grey Seymour, 6th Marquess of Hertford (1843–1912)
• Lady Florence Catherine Seymour (1845–1921), who married Rev. James Blunt and had no children
• Lord Albert Charles Seymour (1847–1891), who married Sarah Napier and had children
• Georgina Emily Lucy Seymour (1848–1944), who married Henry Stirling-Home-Drummond, a maternal grandson of Charles Douglas, 6th Marquess of Queensberry, and had no children
• Lord Ernest James Seymour (1850–1930), who married Lady Georgiana Fortescue, daughter of Hugh Fortescue, 3rd Earl Fortescue and had children
• Lady Constance Adelaide Seymour (1852–1915), who married Frederick St John Newdigate Barne, MP, and had children, including the explorer Michael Barne.
• Lady Mary Margaret Seymour (1855–1948), who married Sir George Dashwood, 6th Baronet, and had children
• Reverend Lord Victor Alexander Seymour (1859–1935), who married Elizabeth Cator and had children

The marquess died in 1884, aged 71, as a result of a fall from a horse at the family home of Ragley Hall in Warwickshire.[2] He was succeeded in the marquessate by his eldest son, and his widow became known as Dowager Marchioness of Hertford. She died at Brooklands Manor, Westcott, Surrey, aged 86.[3]
