[1] Her father was a lawyer who became the member of parliament for Killmarnock in 1769[2] and he owned land in Waterford and Limerick.
[1] Much of the detail of her life comes from a publication titled "The True and Genuine Narrative of Mr and Mrs Tenducci: in a Letter to a Friend at Bath" which was published in 1768.
Her father was keen to marry her to a man her had chosen and Maunsell realised that Tenducci was a possible alternative.
His subsequent biographer Helen Berry was unable to corroborate this claim and suggests that they may have been the children of Dorothea's second husband, Robert Long Kingsman.
She died aged 63 in Grosvenor Place, London and was buried at St George Hanover Square 21 February 1814.
