Peruse and wonder.
Florence Helen Varty, a 19yr. old English girl from Borough Place, Tenterden, Kent, who went to France during the Great War in January 1915 and resided in the Madeleine district of Paris until the December of that year.
The country was in the middle of a bloody war yet life in Paris went on as normal.
Note that her picture on her British passport has been cut from a larger photograph – you can just see a portion of a man's shoulder on the left of the image.
