Lottie, Margot's 10 year old great grandaughter, has written on behalf of her family ... brother George and parents Sarah and Adam. 

She says:  Dear Granna we love you very much and remember when we go to yours then we go to the fish and chips (she adds a drawing of the scene at the riverside restaurant in Benson,  Granna and Lottie are sat at table, plates piled high, Granna's speech bubble says "Yummy"). 

She ends with an invitation to Granna: you could come to me in my dreams and tell me about heaven.
