Born in St Andrews, Scotland in 1837, Barron arrived in New Zealand in 1851. He first spent time as a miner and merchant on the Otago goldfields before engaging in business in Dunedin. He served as Grand Master of the New Zealand Lodge of Freemasons.[1]
He represented the Caversham electorate from 1879 to 1890, when he retired.[2]
