The Correspondence series consists of Victor Marie du Pont's outgoing and incoming correspondence.

The outgoing correspondence is primarily letters to family members, particularly his brother, Eleuthère Irénée, and contains personal detail relating to their earlier years. Includes original letters to his family members, drafts and retained copies of letters sent, and letters received. Aside from personal elements the correspondence offers much relating to Victor du Pont's business affairs, with references to: his shipments of equipment and payments to or for the powder company, his proposed newspaper advertisement of Du Pont powder for sale in the New York market, and his suggestion that his father distribute some shares in the powder company to his stepsister, Mme [Françoise-Julienne Isle-de-France] Bureaux de Pusy, to strengthen the position of his brother, E. I. du Pont, in the powder company; land values and living conditions in Angelica, New York; his hopes for an expanding American woolen market to benefit from declining Spanish flocks, details concerning the financial establishment of the woolen factory, Du Pont, Bauduy, & Co., and the trip to Europe by Ferdinand Bauduy in its behalf; Victor du Pont's role as friend and mediator in the relations between his brother and Peter Bauduy and with Mme Bureaux de Pusy and his financial position in the Brandywine mill complex; the administration of the Wilmington branch of the Farmers' Bank of the State of Delaware; an evaluation of Madison, Henry Clay, James A. Bayard, Sr., and others in national and state politics; and references to Talleyrand's naturalization papers, a fire at the powder factory (1817), the transfer of Company drafts to his father, du Pont de Nemours, in France by means of George de Caraman, the shipment of Du Pont woolens, and allusions to the activities of members of his family and friends (his sons, Charles and S. F. du Pont, his daughter Amelia's marriage, the travels of General [Jean-Victor] Moreau, Baron [Jean-Guillaume] Hyde de Neuville, the Cazenoves, the d'Autremonts, and Mme Bureaux de Pusy.

The incoming correspondence subseries is arranged and labeled by Victor Marie du Pont concerning the settlement of his debts after his bankruptcy by assignment of his estate (including Kentucky lands and Angelica property) to Guilan McEvers, Bertram P. Cruger, and Moses L. Moses, trustees for his creditors. Claims by others, taxes due, a low market price for land, and an unrewarding trip to Kentucky to dispose of the property there disappointed du Pont's hopes for a profitable arrangement of his accounts. The block includes letters to Victor du Pont from Cruger, Moses, William Lovett, Moses and Lovett, Peter Bauduy; also, two deeds for property near Angelica and in Kentucky, single letters from Peter Bauduy to Cruger, William Warner to Moses, and Cruger to Moses, plus du Pont's observations and conclusions on the Kentucky land title (7 pp.), receipts, and miscellaneous records.

The general contents of this group agree with the description made by Mrs. S.F. du Pont in 1880 of one of the "Bundles of Papers that came from Aunt Eleuthera's" [Eleuthera (du Pont) Smith]: "Business papers, Kentucky, Angelica, etc." [Mrs. S.F. du Pont to Henry A. Du Pont, 10 Sep 1880, Winterthur Manuscripts]. The remaining correspondence to du Pont concerns credits owed to or by du Pont firms with G. Manigault, Talleyrand, Mountflorence, Rezeville, Grouchy, and other debtors and creditors, relations between Peter Bauduy and E. I. du Pont, the claims against the powder company by Talleyrand and by Mme Bureaux de Pusy, the sale of English powder in the American market, the powder market in South America, shipments of American seeds to France by Victor du Pont and his brother, investments by the d'Autremont family in Kentucky lands and French mills, details of administration and the release of the du Pont farm near Angelica, New York, effects of the Burr affair in Louisiana on New York business (1807), journey by Raphael Du Planty to New Orleans, a mission by B. Orsele to Mexico to recover French funds, misuse of a letter forwarded by du Pont in an accusation against Mountflorence to a French minister, a subscription by powder workers to pay an immigrant's passage, Pennsylvania property owned by Amelia, du Pont's daughter, and other subjects, and two lists of American plants whose seeds were requested for French botanists.
