Williamson County celebrated the 200th anniversary of its formation in 1999. In honor of this celebration, the Williamson Country Public Library proudly offers a commemorative Pioneer Families of Williamson County, Tennessee Certificate to eligible persons. Anyone directly descended from a pre-1850-pioneer of the county is welcome to apply for this permanent remembrance of their family history and the county's bicentennial. http://lib.williamson-tn.org/P_Main.htm
