Kelly was born in 1855 at Carluke, South Lanarkshire, Scotland. He became an orphan aged 14. He learned the trade of a tailor, and married Elizabeth Millar, the daughter of James Millar of Motherwell in Lanarkshire. The couple emigrated in 1875 on the Aldergrove to New Zealand, landing in Port Chalmers in Otago. They later moved south to Invercargill.
He represented the Invercargill electorate in the House of Representatives from 1890. In 1895, he broke away from the Liberal Party and became an Independent Liberal. He was defeated in the 1899.
Kelly died on 15 December 1938.
