Peter Angel Cemetery is from intersection 699 and 697, go east 2/10 on 699 to cemetery drive on right side of road, cemetery is 1/10 south of 699.Since 1821.This is what the book says.

Have you contacted the Franklin County Historical Society to help you with your Sink Family? They do this on a per hourly basis.
The Roanoke Library on Jefferson Street will get you free obits, just by emailing them.
I hope all this helps. Sorry most were not there.
