Leonard it is easy to find and worth the trip to pay respect to a servant that the Lord has taken to be with Himself
These are the directions I gave two and a half years ago ...
The grave is in square 131 as per the map below ..
Basically you go in the cemetery, and from the gates turn right, staying on the lower path alongside the cemetery border. As this comes to the bottom right corner, it bends around to the left up hill - avoid the much smaller fork off to the right at this point. After 30 meters turn left onto another wide path which visibly rises uphill.
Ten meters up go between gravestones on the left side to join a much less well defined path, passing a very tall monument a couple of metres in. Twenty meters down here, FERs is part of a group just off on the right hand side. It still stands out slightly by being in better condition than average, though no where near as much as it used to be, and on the photos on the website.
The co-ordinates are 51 27.743N, 0 03.241W
