------------------------------------
Milicent de Stafford, who m. in the 5th Richard I, a Staffordshire gentleman of ancient family, named Hervey Bagot. This Hervey paying a fine of 300 marks to the crown, had livery of his wife's inheritance, but in order to raise that sum, he was obliged to sell the lordship of Drayton to the canons of St. Thomas, near Stafford. The son and heir of this Hervey and Milicent, assuming his maternal surname, inherited the estates as Hervey de Stafford.
