Partner in Coulougnac & Cie, a textile firm based in Lyon that also maintained a house in Nantes.

The firm supplied Jonathan Williams with various blankets and fabric, and secured a contract with the state of Virginia. When the firm had difficulty in obtaining payment from Virginia, Franklin apparently met with Coulougnac, and supplied him with a letter of recommendation to Virginia’s governor.

May be the Coulougnac who sent Franklin his reflections on the United States government and constitution, and who hoped to emigrate to the United States and establish a merchant firm near Philadelphia.
