I've been working on a community study genealogy project which is taking a good while(as it should) but I wanted to post about a set of online images I found at FamilySearch. Wilson Creek Primitive Baptist Church Records, 1805-1945 (3 Volumes) Williamson Co. TN. You will need to Log In to see them but registration is free. These records are particularly helpful to anyone who has ancestors of color and / or who wouldn't have been listed as anything other than a tick mark within the household in which they lived prior to 1850 or 1870 if they were enslaved. Folks who had moved to the area brought letters of dismissal which identified where they had previously attended church. Locations I've encountered only 30 images in are Wake Co.NC, Rockingham Co. NC, Warren Co. KY and other TN counties.
