People of Detroit:
Ives Jacques Hugues Pean, Sieur de Livandiere
Ives Jacques Hugues Pean, Sieur de Livandiere was born in Paris in 1682. His parents were Jean Pierre and Anne de Corbarboineau Pean. On June 15, 1722, he was married to Marie Francoise Pecody, daughter of Antoine and Jeanne de St. Ours Pecody.
In 1724, Livandiere was commissioned commandant of Fort Frontenac. Later, he was commandant of Fort Chambly. In 1733, he was made commandant of Fort Ponchartrain.
Documents regarding lands grants made to Pean list his title as "a Chevalier of the Military Order of St. Louis, late captain and now major of Quebec, and commandant at Detroit". Personally, I question the "Detroit" part. It was likely that the documents, unless they were made way after the fact, said "Fort Ponchartrain", rather than "Detroit".
Pean died on January 26, 1747.
Some writers have confused Ives Pean with his son, Michael Jean Hugues Pean. The latter is was involved in a conspiracy (or conspiracies) that eventually led to the French giving up Canada to the British.
