Family History Centers (FHC)are almost the best resource when researching your family tree.

They are part of the Church of Jesus Christ of Latter Day Saints (Mormon Church) yet you need not be a member of the church to use the facilities. If you don't know where your local FHC is located, check this Illinois link. (This link will also provide you access to the "Family Search" web page. Just click the 'Home' button...)
