Sir Edmund Sutton was born in the year of 1425 in Dudley, (d. After 6 July 1483).
By right of his first wife, the family title was passed to her as the third and youngest daughter of lord Sir John de Tibertot, the sister and heir to John, her brother, the Earl of Worcester by her mother, Joyce, being the daughter of Edward lord Cherleton.
Thus it came to pass that through this association the quartering of Edmund of Woodstock, earl of Kent, youngest son of King Edward I came, through the families of Holland, Cherleton and Tibertot to the Dudley family.
