The entry in the diary of Eliza Louisa Marsh-Caldwell reads as follows:

Mr Marsh married secondly in 1792 Frances , second daughter of Mr Graham of Kinross and for some years M.P. for that County. She was a person of a most sweet and gentle disposition and was adored by her step children and could not have been more so had she been their own mother.  Her brother was the Colonel Graham who became a Parnter in our Grandfather's bank and her only and eldest sister married Sir Henry Dashwood, of Kertlington, Oxon.  Lady Dashwood was very beautiful and much about the Court, but had a troubled life, as Sir Henry was a great gambler and often brought his family to great straits and as Lady Ely, his eldest daughter, who married the Marquis of Ely, used to say with tears in her eyes to her uncle (by marriage) our Grandfather, "What would have become of them all but for his kindness, she used to say" and I believe, in truth that at one time he almost maintained the whole Ketlington family.
