the son of Sir Henry Liddell (c.1644–1723) whose seat was Ravenscroft Castle in Country Durham. Other letters survive and from these it is possible to determine Lidell's bitterness towards her sister Mary and her successful marriage to Lord Cowper. She is bitter that her family are not returning the devotion she has shown them. She expected that the Cowper's would have furthered her husband's cause with an impressive position. The Cowper's alternatively believe that they have preferred her husband and they believe that Liddell is not just bitter but ungrateful. Her husband dies in 1717 and she finds that he stands accused of mismanaging his affairs and Lidell takes on the role of his reputation's defender. She refers to Sir James Clavering as "her son" in reference to her history of guarding his inheritance. She was to remain on good terms with him throughout her life although she thought him ungrateful. She is last mentioned in 1735. Lidell's letters are in the UK National Archives.
