I'm looking for free genealogy sites, could you tell me a few?
States I'm reasearching are Tennessee, North Carolina.Family names are Fair/Pharr,and Scales,and Fountain.
I won't repeat the many excellent sources mentioned in other answers, but I will add:
the genealogy message boards at Ancestry.com and Genealogy.com are free:
http://boards.ancestry.com/
http://genforum.genealogy.com/
You can also try the Yahoo Groups for subject GENEALOGY (see URL below) - there are currently 2,834 Groups tagged as "Genealogy"; some Groups are specific to a surname or location or ethnicity, while others are "open non-specific"; many Group members are willing to do free look-ups and help with genealogy questions.
