I think the gentleman in the cap in these three images is Captain James Harold Cuthbert of Beaufront, who was killed in WW1.
Having seen earlier pictures of her I believe the woman to his left in IA0011 and to his right in IA0013 and IA0009 is his first wife Ann (nee Byng) who died in 1907 (accidentally shot by James while out pheasant shooting).
