Hello 'Never give up'
Unfortunately we will not be able to mark the grave 'officially'. This is because our brother was not buried alone. It was custom and practice in those days to bury infants together and because there are others in the grave cut, we can't have a headstone or plaque etc. But we can put flowers down. Also, as in the Peter's entry, we could put a small paving slab down and put an 'official' vase on it, which, considering what is there, would not be out of place. However, yes, you can't do as you like, so we'll see.
Hello Peter
Thanks for the additional posting, I we'll consider the paving slab and vase.
Kind regards
Steve
