The first marriage for Maud (Browning, Charles H. Americans of royal descent. 7th ed. Baltimore : Genealogical Pub. Co., 1986, pg. 201).
The following is an excerpt from Richard Thomson: An Historical Essay on the Magna Charta of King John, London, 1829; Page 311:
"Of the family of Hugh Bigod, or Bigot, some account has already been given . . . since he was the eldest son of Roger, Earl of Norfolk, whose Arms, Or, a Cross Gules, he bore . . ..
"Hugh Bigod succeeded to his father’s estates in 1220-21, the 5th year of Henry III. There are but few particulars of this Baron’s life extant, for he enjoyed the title of Earl of Norfolk but a very few years, since he died in 1224-25, the 9th of Henry III . . .."

3rd Earl of Norfolk and Suffolk, the eldest son, was born before 1195. He was the hereditary steward of the king's household, and hereditary bearer of the Barons of St. Edmund. Not many particulars of this Baron's life have been preserved, as he enjoyed for only a few years the title of Earl of Norfolk and Suffolk, and his father's estates and honors, to which he had succeeded in the 5th year of King Henry III. He died four years later, in February 1224-25. He married Maud Marshal, eldest daughter of William Marshal, 3rd Earl of Pembroke, and his wife, Isabel Clare, daughter of Richard de Clare, the Strongbow, 2nd Earl of Pembroke, and his wife, Eva, daughter of Dermot MacMurcha, King of Leinster, Ireland.
