Described in the contract as "très haut et très puissant seigneur" ("very high and very mighty lord") and the former governor-general of Canada, Pierre de Rigaud had served as a guardian to the bride sometime after the death of her father, a naval commissary stationed in Saint-Domingue (modern-day Haïti), in 1753. At the time of her marriage, the young Mademoiselle Fleury was living in Gennevilliers, now a part of Paris, with Pierre's younger brother Pierre-François (1703-1779), and his wife Louise-Thérèse Fleury de La Gorgendière (died in Saint-Domingue in 1775). Louise-Thérèse was a niece of Madame Pierre de Rigaud and married Pierre-François in France in Québec in 1733. Their five children did not survive past infancy.
Also of interest, as if the reuse of first names (Pierre and Pierre-François are frequently confused and misidentified in secondary literature) weren't bad enough, both brothers are identified in primary sources, including this marriage contract, as marquis de Vaudreuil, a title that, by the rules of the French nobility, only the eldest brother could use; however, eighteenth-century nobles flouted these rules and frequently assumed the same titles as their siblings. Although Pierre de Rigaud was the oldest surviving son of Philippe de Rigaud, marquis de Vaudreuil, in the 1770s, he was even identified as a marquis before the deaths of his two elder brothers. This dual use of the marquisat by both brothers complicates the identity of the marquise de Vaudreuil that some of the documents identify; I have a suspicion that it is more often than not Louise-Thérèse rather than her aunt Jeanne-Charlotte (Pierre's wife), which might throw my hypothesis off a bit as a marquise de Vaudreuil is seeking for restitution of property in what is now Wisconsin as late as 1769. Some of these claims identify the marquise's husband as governor of the town of Trois-Rivières, situated between Montréal and Québec; Pierre-François de Rigaud held this position from 1749 to 1757, during which time he founded a trading post at the Baie des Puants (literally, Bay of the Stinking Ones, or Winnebago Indians), which later became Green Bay, Wisconsin.
A scapegoat for the loss of a New France, Pierre was briefly imprisoned in the Bastille from March to May. Upon release, it seems as though he made his final home in the Parisian parish of Saint-Paul. Inhabiting an hôtel particulier, or private town house, in the rue des Tournelles, Pierre de Rigaud lived a stone's throw from his prison that would be eventually be destroyed in 1789. It was from this residence that he would draft, from memory, an inventory of his effects left at the château Saint-Louis, and write countless letters to ministers, both at Versailles and in London.
Despite escaping this urban renewal of the Second Empire, nothing much exists to inform us about where the Vaudreuil residence might have been. It wasn't until I checked the 1739 map of Paris by Turgot that I saw how much the streetscape had changed. Of course, the Bastille no longer stands. What might have been portes cochères for a few eighteenth-century hôtels, like 17 rue des Tournelles, were the closest things that I could find in the street.
