Major Sir Thomas Livingston Mitchell (June 16, 1792-1855), surveyor and explorer of south-eastern Australia, was born at Grangemouth in Stirlingshire, Scotland. He was educated at the University of Edinburgh, but the poverty of his family following his father's death led him to join the Army in 1811. He saw service in Portugal, where Sir George Murray, later to be Colonial Secretary, was the Army's Quartermaster-General, and became Mitchell's most important connection.

Thomas Bignall Mitchell (often Tom Mitchell or Tommy Mitchell; born September 4, 1902, Creswell, Derbyshire, England; died January 27, 1996, Hickleton, Doncaster, Yorkshire, England) was a leg spin bowler for Derbyshire and easily the most successful slow bowler in the history of a county better known for its pace bowling strength. His bowling was an important factor in Derbyshire's most successful period in the County Championship's long history during the 1930s: along with Bill Copson, Leslie Townsend and the brothers Pope, he formed an attack sufficiently strong during the dreadful summer of 1936 to, aided by some quirks in the weather, displace Yorkshire from their perennial position atop the Championship table.
