Unfortunately I can believe the information that you found, but how do you know it is right? My guess is it was copied from someone else's tree -- how do you know it is correct? Did you check if there were sources? Did you check out the sources for yourself if any were indicated?
If you seriously want to do your family research, this is NOT the way to do it. I looked at a few of your people on the tree, and there is no indication of census records, etc., to support your information.
I totally agree with the other comments that you have to prove or disprove every step of the way - even that is sometimes open to error by conflicting records.
By buying into the other persons tree, it just populates yet more inaccurate information that the next person will copy, and on and on and on. I'm sure the majority of people here will agree that a massive amount of information on the trees out there is bad. My suggestion is to use the trees for clues, but never add a person to your tree unless you prove it with actual records.. not just because someone else says so.
If you seriously want to research your family, there are lots of people here on ancestry and other sites that will gladly assist. Please slow down, prove a generation at a time, and be proud of your work knowing it is right!
