That is a lovley photo of Christinas maternal grandmother. She was born Susan Charlottle Calcraft at Rempstone Hall in 1833, and baptised in the parish of Corfe Castle on 8th November of that year. She married Granville Augustus William Waldegrave, 3rd Baron Radstock in London on 16th June 1858 and thus became Baroness Radstock. They had 9 children, of which the youngest was Mary, Christinas mother.
It is a fascinating family....I've just ordered a book called 'The Calcrafts of Rempstone' which I'm looking forward to reading
