I saw this message before work this morning so I called in to the cemetery this afternoon on my way to an appointment. I didn't have long but I found the right area and found a grave with a number on it just before I had to leave so I know how to work out the row I need to look for now. I'll try to call in again and have a look for you.
I've been for a walk with my dad today so we went via the cemetery. I'm afraid there isn't headstone on S3 44 in that section. I've taken a photo with the one on the next row to it (T3 44) which is for Martin and Edith Dickinson so that you can check I was in the right place. I'm happy to email it to you if you want it.
Please let me know if I was in the wrong place and I'll go back (I can't search the registers at the moment)
