The top-centre picture here doesn't appear to be of my father at all: perhaps it's his father. Anyway, I'll seek clarification.
Update: the pictures on the top row were all taken at Dale Street, Bristol where my paternal grandparents lived and where my father was brought up. Top left is my father, Fred Seel with his niece, Rosalie; top centre my paternal grandfather and a tiny me; top right my father and my teensy self.
