Dugué de Boisbriand, Pierre. Legal document, 1721

This collection is comprised of a legal document transferring ownership of the belongings of Pierre Dugué de Boisbriand to his sister, Marie-Therese Dugué Piot de Langloiserie.

Pierre Dugué de Boisbriand (1675-1736) was a French military officer who served as commander of outposts at Mobile, Natchez, Louisiana, and the Illinois Country. In 1719 he led an expedition to the Illinois Country and established an outpost that became the center of military and civilian activity in the area, positioned eighteen miles north of Kaskaskia. When the third governor of the French colony of Louisiana returned to France after accusations of maladministration, Dugué de Boisbriand was appointed the fourth governor, serving from 1724 to 1726. He was recalled to France to answer to similar charges of mismanagement and was subsequently removed from his position.

This collection consists of a legal document written in French, specifying the transfer of the entirety of Pierre Dugué de Boisbriand's belongings in Louisiana and Canada to his sister, Marie-Therese Dugué Piot de Langloiserie. The document was written at Kaskaskia in the absence of a notary on March 10, 1721, and ratified in Montreal before a notary on March 30, 1722.

The Illinois History and Lincoln Collections purchased the item in September 2018. It was previously in the manuscript collection of Canadian author and bibliographer Lawrence Lande.
