Mary,
Have you looked into Delaware native American history? Also known as Lenni Lenape. I recall my grandfather mentioning Delaware native Americans long ago, and my impression is that he was speaking of our heritage. I was looking here:
https://familysearch.org/learn/wiki/en/American_Indian_Censu...http://www.accessgenealogy.com/native/delaware-tribe.htmhttp://delawaretribe.org/home-page/about-the-tribe/The Delaware River runs near Ulster County, New York, where our ancestors lived. I spend time on this when I can, which is not as often as I would like. If I find something, I will pass it on to you. Let me know if you come up with anything on our Clearwater heritage. Thanks.
Sandy
