Mary was the only surviving child of Lady Elizabeth and Sir Thomas Kitson of Hengrave Hall.
[1] She inherited her mother's collection of music and her possessions including Hengrave Hall.
Her portrait, now in Tate Britain and previously part of Drue Heinz's collection, shows her in pearls, diamonds and rubies which she received for her marriage.
[1] She had been quoted making uncomplimentary remarks about him by jealous court rivals and this and her husband's suspicions led to a deed of separation being created in 1594.
A full-length painting was made of her and in her hand she holds the deed of separation with words "If not, I care not" visible as if to show that she was not heartbroken at the end of her marriage.
[7] Thomas Savage inherited the family fortune thanks to a special remainder that had been added in 1613 to the Barony of Darcy of Chiche.
The special remainder allowed on the failure of his male issue for his riches to go to his son-in-law Sir Thomas Savage, and his heirs.
