Hi,
I have been doing genealogy research for many years and have been to many sites.
Here are sites I've found very useful.
http://www.ancestry.com is a pay site but has some free sections. You can also sign up for a 14 day free trial.
http://www.genforum.genealogy.com allows you to search, and leave messages, by surname and has been very useful to me.
http://www-personal.umich.edu/~cgaunt/gen_web.html is a site that allows you to search for state and county records by first selecting a state then a county
Good luck to anyone looking for their ancestors.
Glenda
