From Leo's Tree:
Above left is the shield of arms for Sir Roger Bigod, Knight. His blazon is:
Or a cross gules
Sir Roger Bigod, circa 1140-11221, Magna Carta Surety Baron 1215, 2nd Earl of Norfolk and Suffolk, Keeper of Hereford castle, Ambassador to kings, Chief Judge in the King's Court 1195-1202.
Second shield above left is the shield of arms for Sir Hugh Bigod, Knight, son of Sir Roger Bigod. His blazon is:
Or a cross gules and a label azure
The father's arms with a label was usually a variation carried by the eldest son. Sir Hugh Bigod, 1178-1225, Magna Carta Surety Baron 1215, 3rd Earl of Norfolk; Earl of Pembroke [in right of his wife].
A note about the arms on the shields: for the Magna Carta Barons, I have used the arms as provided by Reed M. W. Wurts to "Brookfield Ancestor Project - Surety Barons"; and also as shown on banners by the Baronial Order of Magna Charta.
