In 1796, the year he joined his father's bank, Turner married
Mary (1774–17 March 1850), the daughter of William Palgrave of Norfolk. She became a notable portrait artist under her married name Mary Dawson Turner and 78 of her drawings (as
etchings) are in the possession of the
National Portrait Gallery in London. The couple had 11 children: • Hannah Sarah Turner (1808 – ), engraver, married in 1839 Thomas Brightwen, banker. • Dawson Turner (1809 – 1809) • Katherine Turner (1810 – 1811) • Eleanor Jane Turner (1811–1895), the youngest daughter, married
William Jacobson, divine. • Gurney Turner (1813 – 1848), whose son
Dawson Turner played in the first international rugby match in 1871 • Dawson William Turner (1815-1885), educationalist. By his first wife, Turner was father-in-law of Sir
William Jackson Hooker, FRS and of Sir
Francis Palgrave, FRS and the grandfather of Sir
Joseph Dalton Hooker, FRS, the poet and critic
Francis Turner Palgrave, and Sir
Robert Harry Inglis Palgrave, FRS. After his first wife's death in 1850, he married Rosamund Matilda Duff (d. 1863) at
Gretna Green, the marriage being disapproved of by his family and banking partners. He left Yarmouth and moved to Barnes, and in 1853 retired to Lee Cottage, Old Brompton where he lived until his death. Turner's collections were sold off in auction by Sotheby in 1853 earning £4563 15s and another part in 1859 for £6558 9s. ==References==
