I have the complete bartleson family tree beginning around 1803 in grand chain, IL. I think your ancestors come from a different branch.
It is true that a john bartleson was the "Captain" on the original oregon Trail expedition which started in Independence, MO.
His line of bartleson's comes out of Wayne Co., KY. Go to a site called Rootsweb.com and enter Bartleson. You'll be suprised.
