Yes Nigel Canter found it. It's an unmarked grave directly under the large tree to the right as you face the church. There is not much to see, but at least we have found her. The problem was she was buried under the name of Marianne Russell not Mary Anne her actual birth name. Marina was a name that was given to her in her early childhood. To get to Bincombe take the Upwey turn off and turn right rather than left. Then when you have finished your visit turn round and head for the Ship pub for your lunch (car park up the small road to your right) and then Upwey church and the wishing well if you have time. Give all our blessing.
