They left no children. In her will, Lady Sussex left the sum of £5,000 together with some plate to found a new college at Cambridge University "to be called the Lady Frances Sidney Sussex College". Her executors, Sir John Harington and Henry Grey, 6th Earl of Kent, supervised by Archbishop John Whitgift, founded the college seven years after her death.
The mascot of the college is the blue and gold porcupine, taken from the Sidney family coat of arms.
