Where do you find these records online?
I found this site, which lists some states and localities but by no means all. But it doesn't include voter lists for Vermont.

That's okay... you can challenge registrations in any state/locality you find that has the info available. Google "voter records," "death records, "voter registrations," etc.
You will find what you are looking for,
