These were the McKees who were attacked in the Indian massacre of Kerr's Creek.
This is all I can find on the cemetery's location:
"Also called Big Springs Cemetery. Located off Rt 60 on Rt 631 on Clarence Tardy's farm."
I did some searching; Clarence Tardy is dead now. The land was once owned by the McKee family.
If anyone has the address of the farm I'd appreciate it.
