Thank you for your response! I would be happy to exchange information. Also, I have made a contact in Danville, PQ (near Kingsey Falls) who is a descendant of Archibald Cassady. He has done a lot of research, but hasn't linked them together as yet. However, given the fact that John and Archibald were from Kingsey Falls, there is a strong likelihood that they are related. I have been invited to take a trip to the area where I will learn how to conduct research in Quebec, which is different than the US.
