[1] In 1314 at the Battle of Bannockburn, Maud's husband Robert de Clifford was killed.

Her second marriage to Sir Robert de Welle was done without royal licence and this angered the King of England.

She was initially the co-heiress to her nephew's estates along with her sister, Margaret de Clare, Baroness Badlesmere, before the King issued the estates to Lord de Clare's three sisters.

Some say this is due to the fact that she married Lord de Welles without royal licence.

Maud de Clare and her Sister Margaret were the next heirs of their father's estate which included the Stewardship of the Forest of Essex, the town and castle at Thomond and numerous other properties in Ireland.
