Dick VanDuyne was describing his investigation of the Van Duyne family. I don't know if this will help or not, or if they are even related, but in the early/mid 1960s there was an attorney in Morristown by the name of Aaron VanDuyne. I remember him because he was the assistant coach of my Babe Ruth League baseball team (MEPCO) in 1961. He was 40ish then and I have no idea if he or his family is still in the area. I'm sure a city directory/phone book for that era would list him. I'm not sure if the spelling is accurate, but that's how the name was pronounced. Not being a VanDuyne researcher, I don't know if they are all related in some way or if they are common and from many different origins. Hope this helps some ........ Rich in NH
