This pitcher was made between 1810 and 1815 in the town of Sainte Genevieve in what was then called the Illinois Country, an area that corresponds to present-day Missouri and Illinois. The Illinois Country was settled in the eighteenth century by immigrants from France and French Canada, and even after the region was sold to the United States as part of the Louisiana Purchase in 1803, French-Canadian and Creole culture remained dominant. The silversmith Antoine Oneille was born in Quebec and had a peripatetic career in Canada, Indiana, Detroit, and Sainte Genevieve supplying silver for the fur trade as well as for those who profited from it. This pitcher, his most ambitious surviving piece of hollowware, was made for Constance Roy and Ferdinand Rozier, probably around the time of their marriage in 1812 or 1813. Rozier had immigrated to the United States from France in 1806 with his business partner, John James Audubon. The pitcher’s delicate engraving, cast foliate handle, and round belly perched on a narrow foot all derive from high-style French silver and demonstrate the cultural heritage of both its maker and owners.
