Hi Phil
I was at St Clements around about that time but do not remember a benita.
I have copies of the junior school records.
I noticed that you are searching the names Birch and Buckerfield.
I see that there was a Christopher Birch and a Constance and Irene Buckerfield all living at 3/162 Long Acre in 1944. Any relation?
I lived at 10/126 Long Acre then (next to Newtons Factory).
Good luck with the family tree.
