Remember–no site has every record, every file, and every index.
Don’t do all your research via one website, one repository, or one library.
You wouldn’t just use the census only for your research would you?
Expand your research horizons and your family tree–use a resource or a facility today that you’ve not used in a while. You may be pleasantly surprised at what you find.
Fee-based websites may tell you they have everything–they don’t. Even some non-profit websites may suggest they have everything–they don’t.
And remember when you are done with the websites…look offline. Everything is not on the internet.
