The office of Lieutenant Governor of New Brunswick came into being in 1786, when the colony of New Brunswick was split out of Nova Scotia and, at the same time, the government of William Pitt adopted the idea that the new jurisdiction, along with Prince Edward Island, Nova Scotia, and Quebec, should have as their respective governors a single individual. The post Governor of New Brunswick thus came to be occupied by the overreaching authority of the governor-in-chief, who was represented in the colony by a lieutenant. The modern incarnation of the office, however, was established in 1873, upon New Brunswick's entry into Confederation. Since that date, 30 lieutenant governors have served the province, amongst whom were notable firsts, such as Margaret McCain – the first female lieutenant governor of the province – Hédard Robichaud – the first lieutenant governor of Acadian ancestry – and Graydon Nicholas – the first First Nations Lieutenant Governor of New Brunswick. The shortest mandate by a Lieutenant Governor of New Brunswick was John Boyd, from 21 September 1893 to 4 December 1893, while the longest was David Laurence MacLaren, from 1 November 1945 to 5 June 1958.
