Sorry Paul, but your Nan's name doesn't ring any bells with me. I was nearly 17 when we left Soho Avenue, so it is a while ago!
In case there is anyone on this photo that you might recognise, here is a picture of the VE Day party in Vicarage Avenue. Let me know if you recognise anyone, but you were probably too young. Your Nan, uncle and auntie might be on it though. I am the little girl with the dark coat and headband on sitting in the first row of chairs, 6th from right.
