Maud had outlived both her husbands, her first husband Hugh Bigod, 3rd Earl of Norfolk had died in 1225, he was, along with his father Roger, listed as being the first two men (among twenty-five) to enforce Magna Carta. Maud's second husband was William de Warenne, 5th Earl of Surrey who died in 1240. Warenne was one of the few barons who remained loyal to King John.
This must have put Maud in a bit of a position.
Maud Marshall was in her late fifties when she died, she is buried at Tintern Abbey in Monmouthshire.
My photographs were taken two weekends ago at Framlingham Castle (there was no sign of Maud)
