Family at Pool dig

Now my memory might not be 100% on this but this photo was taken at the Open Day at the dig at Pool in Sanday by Dr John Hunter. I have a feeling it was the same day as Mum had her birthday but that might have been another year. Judging by the size of the 'trench' it was the second or third year the 'diggers' were in Sanday which puts it at 1984 or 85 (I think).
