I also am a Hadsell, I will have to get ahold of my sister but I know they got a book that was published years ago from a Hadsell who I think lived in California who traveled around to gather info on all the Hadsells at the time. My sisters name is in the book she was born in 53 but I am younger and mine isn't. If I can get the info from her I will post it here about the book.
