Biography

In 1722, Melusina was created Baroness Aldborough and Countess of Walsingham as a life peer. After the death of her father in 1727, she lived mainly with her mother at Kendal House in Isleworth.
In Isleworth, Middlesex, on 5 September 1733 Melusina married Philip Stanhope, 4th Earl of Chesterfield, a leading Whig Party|Whig] politician. The couple had no children, but it is said that "family letters" suggest that Melusina may have been the mother, through an intimacy with Charles [Calvert, 5th Baron Baltimore], of Benedict Swingate Calvert. Calvert was born in England in around 1730–32, the illegitimate son of the 5th Baron Baltimore, while his mother's identity is otherwise unknown.
