Unfortunately, I cannot read french. I have a book called "LES QUESNEL 1488 - 1983 Du Chateau de France a l'Amerique Volume 1" Les Editions Quesnel de Fomblanche editeur Albert Aime Quesnel. Albert Aime did a very extensive research on the Quesnel family name starting from 1488. It is very interesting reading... if I could only read french. He has listed all his reference materail and where he retrieve his info for is research. This is where this info on the board is from his book. Are you able to translate?
