Source <The dormant and extinct baronage of England: or, An historical and ...> Par Thomas Christopher Banks:
This ancient family is faid to have its rife from the Blondi or Biondi, in Italy, whose historians derive them from the Roman Flavii.
Blound, lord of Guisnes, in France, had three sons, who came into England with the Conqueror. One returned into France again; the the other two, Sir Robert and Sir William, remained. Sir Robert at the time of the General Survey, possessed several lordships in the county of Suffolk, of which Ixworth or Ikesworth, was the chief of his barony. Sir William had several lordships in Lincolnshire: but Sir Robert was father of Gilbert, who, by Alice de Colkirke, his wife, had issue, William baron of Ixworth, who, by Sarah de Montchensi, his wife, was father of another Gilbert (by some called Hubert), who, by Agnes de Lisle, had two sons, William and Stephen. William the eldest, married Cicely de Vere, and had issue another William, and two daughters; which William being amongst the rebel barons, temp. Henry III. and standard-bearer in their army, under Simon Montfort, earl of Leicester, was slain with him at the battle of Lewes, leaving his two sisters; viz. Agnes, Wife of Sir William de Criketot; and Rohese, of Robert de Valoines, (vid. Criketot, and also Valoines,) his heirs, who shared the inheritance."
