I am a descendant of John DuBay and Calista. You can find a lot of information near Knowlton Wi as he has a lake named for him. Lake DuBay. He also has a marker at his grave in Knowlton. He was an interesting man and I have a lot of information about him. and even a book written about him. I met his daughter, Minnie, when I was about 8 and she lived with a Mrs. Jessee just off Grand Ave in Wausau Wi. Aunt Minnie was 93 at the time. You need to check records from Portage Wi and also from the Eau Plaine Census. We descend from Heron (or Hurm as listed in documents) who married a Hayner. It is worth the search as John DuBay was a very INTERESTING man. One story has him riding his horse into a court room in Madison WI and tossing down his fine. He also was involved in a murder trial which deadlocked twice. John was a trader, trapper, interpertor for a govenor of Wi, treaty maker with the Indians, and on and on.
