Perrault, M. (Guillaume-Michel), 1726-1790.

Two Perrault brothers, Guillaume-Michel and Jacques, acquired the seigneurie of la Bouteillerie (also called Riviere-Quelle) in 1774, and it passed to Guillaume-Michel in full upon Jacques' death in 1775. Guillaume-Michel's sister-in-law, Charlotte Boucher de Coucherville, continued to run the seigneurie while Guillaume-Michel pursued other investments, including a plantation in New Orleans. When Guillaume-Michel died in 1790, he left the Canadian seigneurie to his nephew, Charlotte's son, Jacques-Nicolas Perrault (1750-1812) with its benefits going to Charlotte until her death in 1792.

The author of the letter, Guillaume-Michel Perrault, could be related to Charlotte Perrault, the wife of Charles Laveau Trudeau. Charles (or Carlos) Laveau Trudeau was one of the leading politicians in Louisiana during the Spanish colonial period and the early territorial period; he was also grandfather to the "voodoo queen" Marie Laveau. Before he married the French-Canadian Charlotte Perrault, he had a brief relationship with one Marie Laveau, who had a free male child with him named Charles Laveau (father to Marie Laveau, the Voodoo Queen).
