Sorry, I could not find a John during that time period in my family. However, I have kept some old records of other Bartons in NY and Vt in storage that turned out to be dead ends for me. I will put your letter in my files and if I find any reference I will be glad to send it. I know how frustrating it can be to know that an individual exists but you cant find him or her. Best of luck in your search Lea
