Dunn Baronets
There have been three creations of baronetcies on families bearing the surname Dunn; all three were in the Baronetage of the United Kingdom. The first was settled on William Dunn of Lakenheath, Suffolk, for whom the Sir William Dunn Professor of Biochemistry and the Sir William Dunn School of Pathology at Oxford University are named. This creation became extinct upon his death in 1912.
A second creation was made in 1917 for William Henry Dunn, Lord Mayor of London. This creation became extinct upon the death of the second baronet in 1971.
The third and final creation was in 1921 for James Hamet Dunn, 1st Baronet, the Canadian financier and industrialist. This creation became extinct in 1976.

In 1933, Dunn married Lady Mary Sybil St. Clair-Erskine, daughter of James St Clair-Erskine, 5th Earl of Rosslyn, with whom he had two daughters: Serena Mary (b. 28 April 1934), who married Jacob Rothschild, 4th Baron Rothschild; and Nell Mary, Mrs. Jeremy Sandford (born 9 June 1936), who became a playwright and author. The baronetcy became extinct on Dunn's death in 1976.
