Hello Tiggercat,
The section you are looking for is below and to the left of the Chapel, right next to Wainhouse Tower.
Go down the path between the old chapel and the graveyard, and when you get to the bottom, cross the lane and bear left down the slope into section F.it is overgrown at first, then all the graves come into view, the rows etc are numbered from the far end, nearest Wainhouse Tower.
The grave is on the 10th row up from the tower end, and 9 in the row.
The first grave on the row you are looking for is a Webb grave, the graves on either side of yours are,Stott on the path side and Bridge on the far side.
If you need any more help get back in touch,
Regards,
Andy
