Captain Henry Wolsey Bayfield (1795-1885) was born in Kingston Hull, England. At age 11 he entered the Royal Navy. He moved up in rank and served in the Mediterranean, off the coasts of France, Holland, and Spain, in the West Indies, and at Quebec and Halifax before joining the British flotilla on Lake Champlain in October 1814. He became acting lieutenant in Kingston, Upper Canada, on the sloop Star, a vessel employed in the Royal Navy’s surveying service on the Canadian lakes under the command of Captain William Fitz William Owen. Bayfield assisted Owen in the summer of 1816 in the survey of Lake Ontario and the upper St Lawrence from Kingston to the Galop Rapids at Edwardsburg Upper Canada. Bayfield soon became in charge of surveying. Bayfield was promoted commander in 1826. While in England he persuaded the Admiralty that a survey was required of the St Lawrence River and Gulf, to be connected with the chain of surveys from Lake Superior eastward. The Admiralty appointed Bayfield superintendent of the St Lawrence survey in 1827. One of Bayfield’s special concerns was to obtain measurements of the distances between the meridians of Quebec, Halifax, and St John’s. By 1848 Bayfield had surveyed the entire coastline of Prince Edward Island the Northumberland Strait coast of Nova Scotia, and the northeastern extremity of the Gaspé. In the next five years, he concentrated on a survey of Cape Breton Island begun in 1847, the Strait of Canso, Isle Madame, and the Bras d’Or Lake.
