The Armand Duplantier Family Letters date from 1777 to 1841 and contain items from four generations of the Duplantier family, including Armand Duplantier, his uncle Claude Trénonay, Armand’s son Armand Allard Duplantier, and granddaughter Amélie Augustine Duplantier Peniston. The collection’s historical significance lies not only in what it can tell us about the history of Baton Rouge and nearby Pointe Coupée Parish, but also in what it reveals about the state’s colonial period, Francophone Louisiana in the territorial and antebellum era, and the enduring legacy of the state’s French antecedents.
In particular, the letters relate to Louisiana under the French, Spanish, and Americans and the economic, political, and social conditions attendant on transitioning among the three powers; commerce with France; the succession of Trénonay; attitudes about the French Revolution; slavery and plantation matters; family news such as illness, births, deaths, and the education of Duplantier’s children; and travels in France by Amélie Duplantier.
Armand Duplantier, Sr., whose letters represent the bulk of the collection, was born in Voiron, France, in 1753. He served as aide-de-camp to the Marquis de Lafayette during the American Revolution and came to Louisiana in 1781 to assist his uncle, Claude Trénonay, in running his plantation in Pointe Coupée Parish. Soon after his arrival, he married Trénonay’s step-daughter, Augustine. He continued to manage his uncle’s interests, purchased and sold additional slaves and land in Pointe Coupée, the Felicianas, and the Baton Rouge area, and raised cotton, indigo, and tobacco. He also developed land holdings in New Orleans, where he lived for a time. Soon after his wife’s death of yellow fever, in 1802 Duplantier married Constance Rochon Joyce, the widow of John Joyce, the original owner of Magnolia Mound Plantation near Baton Rouge. Failed crops and poor investments led him to declare bankruptcy in 1814.
In addition to his planting activities, Duplantier was somewhat involved in public life. His friendship with Lafayette had continued after the Revolution, and when Lafayette was granted lands in Louisiana in 1803 in recognition of his service during the American Revolution, Duplantier was charged with acquiring them. He was also part of the delegation that welcomed Lafayette during his 1825 visit to Louisiana. Always concerned about suitable educational opportunities for his own children, he helped establish Baton Rouge College in 1822. He died five years later and was buried in Highland Cemetery with military honors.
The Armand Duplantier Family Letters were given by the descendants of Guy Antoine Allard Duplantier, elder brother of Armand Duplantier, to their Louisiana cousins, and subsequently donated to the LSU Libraries in 2011.
