(1930) Sarnia: the county-town of Lambton county, Ontario, and township of that county, instituted in 1835. Sarnia is the name the Romans gave to the island called Guernsey. Sir John Colborne had been Governor of Guernsey before he was appointed Lieut-Governor of Upper Canada. In 1835 Sir John visited this district and was asked to give a name for the new settlement. He suggested the old Roman or Latin name for the Channel Island from whcih he had recently come. Sarnia was incorporated as a city in 1914.
