Pierre-Joseph Céloron de Blainville — also known as Celeron de Bienville — was a French Canadian Officer of Marine. In 1739 and '40 he led a detachment to Louisiana to fight the Chickasaw in the abortive Chickasaw Campaign of 1739. In 1749 he led the 'Lead Plate Expedition' to advance France's territorial claim on the Ohio Valley.

Michilimackinac is derived from an Ottawa Ojibwe name for present-day Mackinac Island and the region around the Straits of Mackinac between Lake Huron and Lake Michigan. Early settlers of North America applied the term to the entire region along Lakes Huron, Michigan, and Superior. Today it is considered to be mostly within the boundaries of Michigan, in the United States. Michilimackinac was the original name for present day Mackinac Island and Mackinac County.
