- not to be confused with Grace Marks' employer who died in 1843
He was born on 11 January 1796.
His father was Charles Kinnear, an agriculturalist in Fife. His grandfather Thomas Kinnear was also a banker and founded T. Kinnear and Sons in 1748. Kinnear’s was one of the few Scottish banks to survive the crisis of 1772.
After his death his widow is listed as living at 44 Melville Street in Edinburgh’s West End.
The National Archives in Kew hold a copy of his will, dated 21 February 1831. After his death his firm amalgamated with Donald Smith and Son to form Kinnear, Smith and Company (1831). Smith had been Lord Provost of Edinburgh 1807-08. Due to mismanagement of funds this company failed disastrously in 1833/4, leaving debts of £320,000.
His nephew was the lawyer James Kinnear.
