thanks Philip, it was amazing, very moving and humbling. I have to say to all on this forum, first of all thank you for the help, it will be duly noted in my novel. Other points that may help other visitors....
1. There are several cemeteries in the region and they are extremely difficult to access by public transport, I did it but it included a 10km walk, one serious suggestion is hiring a car.
2. the cemetery records may not be accurate, the grave i searched was not at the reference on the records, that meant me searching grave by grave
3. Bancourt, not sure about the others, has nobody there to help so you are on your own.
If anybody wants any advice on how to get there I am more than happy to help. Thanks again to everybody that helped.
