“ Outside Oxford Kettell held the rectory of Garsington, which was attached to his office of president, and was private chaplain to Sir Francis Walsingham's widow and to Bishop Bilson of Winchester. Aubrey, who was admitted a commoner of Trinity in 1642, and knew Kettell in his old age, narrates many anecdotes of his eccentricities, and quotes specimens of his quaint remarks. Aubrey also mentions his secret charity to poor scholars, and his contemptuous treatment of the strange visitors whom the civil wars brought to the university. ”
