“ MANNERS, EDWARD, third Earl of Rutland (1549–1587) , born in 1549, was eldest son of Henry, second earl of Rutland [q. v.] , by Margaret, fourth daughter of Ralph Neville, fourth earl of Westmorland. He seems to have been educated at Oxford, though he did not graduate there as a student. He bore the title of Lord Roos or Ros, the old title of his family, until 1563, when by the death of his father he became third Earl of Rutland. He was made one of the queen's wards, and was specially under the charge of Sir William Cecil, who was connected with him by marriage. ”
