By now you have probably found your Knowlton connection. I just found out mine recently. Nahum Clark's wife was Rachael Knowlton. She is buried in a cemetery in Hubbartown/Hubbarton, Rutland County, Vermont. She was James McRoberts' mother-in-law. James married Prudence Clark. That makes me related twice to the Clark/Waite limbs on my family tree.
