It was during this last visit to his home in France that Audubon's sister, Rosa,[112] was married to Gabriel Loyen du Puigaudeau, who was not, however, as the naturalist has stated, either "the son of a fallen nobleman" or his father's "secretary." Du Puigaudeau came from a family of merchants in easy circumstances, and for a long time lived the life of a country gentleman of leisure—for a period at Port Launay, below Couëron, and later, after Lieutenant Audubon's death, at his own villa, "Les Tourterelles," in that commune, not far from "La Gerbetière." His father, though of a rich family, was not a "gentleman," that is, a member of the aristocracy, as the term was then used in France. Du Puigaudeau was without any settled business, but his revenues, upon which he depended, failed not long after the death of his father-in-law. He and young Audubon appear to have been good friends for many years, and after the latter's return to America they corresponded to as late as 1820, when for some reason their relations were broken. In the spring of 1806 Lieutenant Audubon arranged a business partnership between his son and Ferdinand Rozier, to endure for nine years, and also secured passports for both to enable them to emigrate immediately to the United States. To the same hand can also be traced their "Articles of Association," which were drawn with the utmost care and designed to govern them in all their future business relations in the New World: these were signed by "Jean Audubon," and "Ferdinand Rozier," at Nantes, on March 23, 1806. Moreover, eight days before they embarked, a second and more elaborate letter of attorney was issued to them jointly by the Lieutenant, his wife, and, in this instance, the aged father of Ferdinand, under date of April 4, 1806.[113] According to the terms of this admirably executed paper the partners were entitled to conduct all the affairs of the grantors in reference to their property in the United States to the best of their judgment and ability; to carry on the "Mill Grove" farm, to the extent of their part ownership in the estate, or to dispose of this interest; "to exploit or cause to be exploited the mine recently discovered on the said farm, to consult in every important matter Mr. Miers Fisher, merchant of Philadelphia,—as a common friend and good counsellor, to keep all necessary books and registers, and at the end of each year, or sooner, to strike a balance of the receipts and expenses of the said farm and the exploitation of the mine, should there be reason for it."
