Granted soon after the Conquest to the family of de Talebois, barons of Kendal, and held by them of the fee of Workington.
The name in ancient documents is variously written Haverington and Haveringham, and presumably impressed itself upon the possessors of the manor, the Harringtons.
There were several branches of this family; one was resident at Beaumont, in this county; another at Witherslack, in Westmorland; a third at Aldingham, in Furness; and two other branches in the counties of Rutland and Lincoln.
In the early period of our history the barons of Harrington appear to have held a position of consequence and importance among the English nobility. The first of this family who held Harrington married the heiress of Seaton, in Camerton. The next upon record is Robert de Harrington, who married the heiress of William de Cauncefield, whose father had married Alice, heiress of Sir Michael le Fleming. Several of the early Harringtons were summoned to Parliament; and one, Sir Robert, received the honour of knighthood at the coronation of Richard II.
The estates subsequently became the property of Thomas Grey, Marquis of Dorset, by his marriage with the heiress of the Harringtons. Henry, his grandson, third earl, married Frances, daughter and co-heir of the Duke of Suffolk, by Mary, sister of Henry VIII, and dowager Queen of France. Henry was afterwards created Duke of Suffolk, and in the reign of Queen Mary he was convicted and attainted of high treason, for his attempt to place the Lady Jane Grey, his daughter, on the throne at the death of Edward VI. He was beheaded, and likewise the unfortunate Lady Jane, and his estates forfeited to the Crown.
The Manor of Ennerdale: A portion of the manor was given by Ranulph de Meschien to the priory of St.Bees, and the remainder passed successively to the families of de Harrington then the de Bonville’s and finally the Grey’s. This area was forfeited to the crown in 1554 by Henry Grey the father of Lady Jane Grey.
