Vasseur, Charles, the grantee of Park lot No. 6, Tiny [Simcoe County, Ontario, Canada], in 1834. He was born at St Maurice, Quebec, served with the "Voltigeurs," then went west with the Hudson's Bay Company. He joined the British forces and was at the capture of Mackinaw in 1812. There were six brothers and all went to Mackinaw and followed the British to Drummond Island, thence to Penetanguishene. While at Mackinaw Charles married a young half-breed woman named Marguerite Langlade, a near relative of the famous Captain Langlade and cousin of the Langlades of Tiny.
More about the Vasseur family from The Northern Peninsula of Michigan:
Louis C. Vasseur. — A venerable and respected resident of Ontonagon, Louis C. Vasseur has lived in this section of the Upper Peninsula for more than forty consecutive years, during which time he has been an interested observer of the many wonderful changes that have taken place in the face of the country, watching with pride and satisfaction its growing prosperity. A son of the late Charles Vasseur, Jr., he was born, October 19, 1829, in the village of Pentanguishine, Simcoe county, province of Ontario, Canada, of French descent.
His grandfather, Charles Vasseur, Sr., was born, bred, educated and married in Paris, France. Emigrating to this country, he followed his trade of a silversmith in New York City for a time, but subsequently followed the pioneer's trail to the northwestern territory, locating at Green Bay, Wis., when there were but few white settlers west of the Ohio river. Establishing a trade with the Indians, he continued his residence there until his death. His oldest son remained in France, but two daughters came to this country with him and his wife, and their other son, Charles, Jr., was born at Green Bay, Wis.
