In the background is Well House, unchanged to this day. The Keyser family can be more clearly identified in the next photo, but the gentleman in the long pale overcoatt (a coachman's cloak?) and top hat on the extreme left of this photo is most likely their Coachman- he appears in the next photo below driving a carriage, in identical dress.
This photo hanging Aldermaston Parish Hall depicts the ceremony on the Loosey when the water system installed by Mr Keyser was turned on. Well house can be seen in the background and the Keyser family can be identified- Charles wears a straw hat to the left of the fountain, with one of the familiarity’s Pekinese. Hos wife Emma and their three daughters are all dressed in white, be hing and to the right of the water-spout.
