for having failed to affix the seals to the decree of 5 July 1714, condemning a document by the Bishop of Metz, Henri-Charles de Coislin, as contrary to the papal bull Unigenitus. He had found it difficult to reconcile his religious beliefs with those of the increasingly authoritarian Louis XIV. He retired to an Oratorian institution where he died in 1727. Personal life In 1668 he married Marie de Maupeou. They had one son, Jérôme Phélypeaux (1674–1747), comte de Pontchartrain. Legacy Lake Pontchartrain in Louisiana was named after him, as well as the historic Hotel Pontchartrain in New Orleans. In Michigan his name was given to Fort Pontchartrain du Détroit (the site of modern-day Detroit), and to Detroit's Hotel Pontchartrain. Isle Phelipeaux, Isle Pontchartrain, and Isle Maurepas, which appear on early maps of Lake Superior, were named in his honor by Pierre François Xavier de Charlevoix. It was later determined that Phelipeaux did not actually exist, and it is uncertain whether Pontchartrain and/or Maurepas refer to real islands known today by other names.
