Agnes Howard (née Tilney) (c. 1477 – May 1545) was the second wife of Thomas Howard, 2nd Duke of Norfolk. Grandmother Haney Side. Two of King Henry VIII’s Queens were her step-granddaughters, Anne Boleyn, and Catherine Howard. After her mother’s death, Catherine Howard was in the Dowager Duchess’s care during her youth, and as a result of the Duchess’s lax guardianship, committed sexual indiscretions while in the Duchess’s household which led to her execution as Queen. Agnes’ brother, Sir Philip Tilney of Shelley (d.1533), was the paternal grandfather of Edmund Tilney (1535/6–1610), Master of the Revels to Queen Elizabeth and King James. Edmund Tilney’s mother, Malyn, was implicated in the scandal surrounding Queen Catherine’s downfall.
