I wonder whether this shows a member of the family of the then (in 1923) present owners of Somerville? This view is looking generally westwards, lengthwise of the main drive, towards the Banbury Road, past the house’s front porch whose entrance pillars are at the RHS. Behind the photographer is the rear garden, the garage and outbuildings, and on the LHS of this view, across a band of grass and some shrubbery beds, is the south-side (Oxford side) boundary wall, extending up to the Banbury Road.
