Notes for William Marshall
The young
From 1228 on, William was mostly in England and high in the king’s favor, and in August 1230, he accompanied the king to Brittany. William stayed in Brittany with Ranulf of Chester until February 1231, when he returned to England. In March of that year William arranged the marriage of his sister Isabel, widow of Gilbert de Clare, to Richard earl of Cornwall and brother to King Henry III. A few days after this marriage, William Marshal the younger died on April 6, 1231, at about the age of forty. There are no records of how William died, but Matthew Paris in his chronicles writes that later in King Henry III’s reign Hubert de Burgh, justiciar of England, was accused of poisoning William Marshal. There are no other sources that agree with this, and there are no other records or chronicles that give any additional information regarding William’s death. William was buried near his father in the Temple Church in London on April 15, 1231.

Notes for Eleanor (Spouse 1)

On April 23, 1224, William Marshal married the sister of King Henry III, Eleanor. She was only nine at the time of this marriage, and it seems that King Henry III married her to Marshal to keep Marshal from marrying into either a Normandy family and increasing his ties to his brother Richard or into the de Brus family and strengthening his ties to Scotland. One has to wonder what William’s father would have thought of the marriage of his son to a child of King John. William Marshal senior had always been aware of the delicate balance of power between a feudal baron and his king as overlord. It is very probable that William senior would have strongly disapproved of his son marrying into the royal family because it would have severely limited his son’s ability to remain a baronial check against the possibility of royal abuse of law and power.
