Margaret Stanley, Countess of Derby (née Lady Margaret Clifford; 1540 – 28 September 1596) was the only surviving daughter of Henry Clifford, 2nd Earl of Cumberland, and Lady Eleanor Brandon. Her maternal grandparents were Charles Brandon, 1st Duke of Suffolk, and Mary Tudor, Queen of France. Mary was the third daughter of King Henry VII of England and Elizabeth of York.

Early life
Margaret was born at Brougham Castle in 1540. Her mother died when she was seven and her father left court.
Claim to the throne
According to the will of Henry VIII, Margaret was in line to inherit the throne of England. Upon the death of her mother, Margaret became seventh in line. However, both her cousins Lady Jane Grey and Lady Mary Grey died without issue, and their sister, her other cousin, Lady Katherine Grey, died without the legitimacy of her two sons ever being proven (this was later established but only after the death of Elizabeth I). Margaret quickly moved up to becoming the first in line to the throne but died prior to the death of Elizabeth I.
