Just saw your post in the Ancestry.com message boards. I don't believe that the Cozzens in Windham CT were Native American especially associated with Joseph Tucker IV. He married Nancy Chaffee who was thought to be Nancy Cozzens but was not. She had an illegitimate son named John Cozzens who Joseph Tucker raised. I believe the father was a Charles Cozzens.

I have quite a bit of info if you're interested in that direction
