フォンテーヌブローの勅令
Du Casse admitted his family's religious background in a letter to Naval Minister Pontchartrain in 1691, and local records from Pau also support the Huguenot origins of the du Casse family. He renounced his Calvinist faith in 1685, however, after Louis XIV revoked the Edict of Nantes via the Edict of Fontainebleau.
