He was the Seigneur de Boyeffes, Galois, Trehoult and de la Bourse. In HEATH'S FRENCH DICTIONARY, an early French publication with wide coverage of early French words, "bourse" was defines as a hair bag or purse. Also named was the French stock exchange. From these definitions, one can imagine that the estate of la Bourse might have been a productive source of agricult- ural wealth for the holders. La Bourse is located on the Michelin map of France, slightly south of Belgium, next to Noyelles.
