I am also researching Lashley family. I have found a church in Caswell Co that has a tombstone with the name Powell Lashley. His wife and 2 daughters are also buried there.
The church is a Methodist church but has no services now.
I'm not sure of the name of the road, but I think it is Pleasant Grove Church Rd. It is off of Hwy. 119 out of Mebane,NC. The tombstones are in the old part of the cemetery. You can email me if you would like about this.
