We know about Elizabeth from the following:
1. Bourke's 1886 which records the Caldwell family of Linley Wood.
2. Anne Marsh-Caldwell's diary.
3. Her portrait, her portrait by Gardner.
4. The book "Thomas Bentley 1730-1780 of Liverpool, Etruria and London" published in 1927.
5. Mention on the memorial in St.James's church in Audley which states that she 'died April 9th 1831, aged 76 years'.
According to Bourke's, Elizabeth together with her sister Hannah inherited money from a cousin of their mother's. It is not entirely clear but it would appear that it was from Samuel Crompton of Derby and/or Henry Coape of Duffield. We know from the book "Thomas Bentley 1730-1780" that Elizabeth also inherited some of Thomas Bentley's estate and we know that Bentley's portrait was at Linley Wood when it was sold in 1949.
Ann Marsh-Caldwell in her diary notes that Elizabeth and her sister Hannah benefited from a number of legacies and inheritances amounting in total to £20,000 which was at the time presumably quite a considerable sum.
In her diary Anne Marsh-Caldwell mentions her mother Elizabeth as follows: "She was of middle stature, and in her youth, I believe, had been very slender and of a beautiful figure, but I only recollect her very full in the figure. Her complexion was rather olive. She had no colour; her features, with the exception of the most beautifully formed nose that I ever beheld, could scarcely be called regular. She had high cheek-bones, brows a little too low and eyes placed rather too deep; her mouth not noticeable for its form, but with an expression of sweetness and affection such as surely no other mouth ever expressed. The whole countenance had a most charming effect taken together - so much sense, sweetness and humour surely never were expressed. Its predominant expression however was as sweetness, or rather a tenderness quite unrivalled. She must have been 39 when I was first old enough to remark her - so that I could never have an idea of what she had been in her bloom, when I believe from traditional accounts she must have been excessively admired."
Anne goes on to describe Elizabeth as follows; "My mother was the woman complete - strong in courage, intrepid in danger - firm to her own purposes, interested, lively, witty, humorous - but melting to love and glowing with tenderness for the husband of her heart and the children of her bosom." Elizabeth moved from Newcastle to Linley Wood, with her husband James Caldwell and their children, in about 1794 and she lived there up until her death in 1831.
