The Cache is not at these co-ordinates.
The above co-ordinates should lead you to the first set of information you need. However, if you enter the graveyard, continue through to the next field and turn right, heading down the concrete path towards a bench. Here you will find a headstone with three flowers on marking the final resting place of Cynthia and “Frank”.
Find the date that Cynthia passed away. 19.11.199C
On your way back out of the graveyard look for the resting place of Roy Skelley. He is fairly nearby (a few rows back and on the left).
Find the date that Roy passed away. AB.03.2009.
The cache can be found at the following co-ordinates.
N50 23.AB9
W003 55.8(C+A)C
Happy Caching 
Congratulations to "Lambs of Cleeve" on being FTF!!!!!
