I'm not part of your family, but while looking for other family members, I came across a Pritchett/Ursery Cemetery on Hester Beasley Road. It's in Davidson County, about 3 miles from the Williamson County line. I grew up in that area, & never heard of this cemetery, so it has to be old. Some graves go back to the 1800's. Not sure if this helps, just passing along the information.
Good luck with your search. Kelly
