Brothers Valsin and Oscar Vignaud worked together to import fine French porcelain for their Creole customers in the French Quarter. Valsin was a successful merchant with a stake in the armed brig Venus, which carried freight across the Atlantic Ocean. While Valsin handled the shipping, Oscar managed the chinaware and fancy goods store on Chartres Street, which they had established by 1838.
