Source Internet : www.quesnels.com/history.htm FRANCOIS-PROSPER QUESNEL (1750-1817) married Victoire Delavigne in 1778 and continued the family textile business in Rouen with his brother Louis-Thomas, who married Victoire's sister, Marie-Thérèse. (The Delavignes were big landowners.) He was an alderman of Rouen, administrator of the city's hospitals and a King's Counsellor. He was nicknamed the Magnificent because of his great fortune and high lifestyle (measured in horses, apparently, of which he had 15-20). When the French Revolution struck, he had to send his three children to England for safety, but he himself remained in Rouen, was taken prisoner and barely escaped execution, being saved by the intervention of a cousin. His children were a daughter, Victoire, and two sons, Edouard-Prosper and Louis.
