Here are locations I got from a man in my church who is from Anson county.
I have two Flake cemeteries in Anson county listed in my files.
The first is the old Samuel Flake cemetery on Smith creek. My directions are:
From Lilesville go north on 1703 for .7 mile.
Go right on 1704. go 1.5 miles.
Go right on 1741 go 2.2 miles.
A logging road goes both ways. Take the one going to the right downhill to the creek (about 1/2 mile). When I was there there were trees down across the road and ditches in the road so we couldn't drive down.
When you get to the creek the cemetery is about 100 feet to the left.
There is only one large marker which reads - if I remember correctly - Samuel Flake 1701-1802 his wives and his slaves.
It was placed not long ago by his descendants.
The other is the Allen - Flake Cemetery.
My directions from the cemetery book (or film)are: 4.5 miles north from Wadesboro on 515. Visible from the hwy beyond Birmingham Hough School.
I don't see a highway 515 on my maps. I am guessing that highway 515 is now NC 742. The school is probably gone.
Looking at the NC Atlas and Gazeteer - like you have - it would be pretty close to Brown Creek which I heard you mention the other night.
If they are talking about what is now US 52 then it is closer to Goulds Fork of Brown Creek.
A copy of an old map of Anson county dated about the same time as the cemetery book would help.
