John Gardner Kinnear was a member of the ill fated firm of bankers, Thomas Kinnear & Sons, which collapsed in 1833. He afterwards worked for Henry Watson & Co., merchants of Glasgow, and was Secretary of the Glasgow Chamber of Commerce. In 1841 he published a book about a business trip he had taken two years earlier in the Levant.
Some family trees show John and Mary had another child named Donald.
