When Lady Anne’s father, George died in 1603, he left a will in which his younger brother inherited the Clifford estates in Westmorland and Yorkshire and became 4th Earl of Cumberland. As a woman Anne was not allowed to inherit the title but the estates had been entailed to heirs male or female in the early 14th Century. Lady Anne, supported by her mother fought, without success, through the courts and petitioned the King to get the inheritance which was legally hers.
Lady Anne married twice: Firstly Richard Sackville, 3rd Earl of Dorset, with whom she had five children but only two daughters, Margaret and Isabella, survived; Secondly to Philip, Earl of Pembroke & Montgomery.
Eventually Lady Anne, on the death of her uncle and cousin, without any further male issue, in 1643, gained her inheritance. However, it was only in 1650 when her second husband, Philip, died that she had sufficient funds at her disposal to begin the huge programme of repairing and rebuilding five castles and seven churches on her estates in Westmorland and Yorkshire.
Lady Anne spent most of the last 20 years of her life at Brougham Castle travelling around the area visiting her tenants and friends.
