Remarks:
From BRITAIN'S ROYAL FAMILIES, by Alison Weir:
Roger Mortimer was the 1st Earl of March. He opposed Edward II and the Despencers in the wars of 1321-22. He escaped to France where Queen Isabella, Edward's official Queen Consort, became his mistress. They invaded England and forced Edward II to abdicate January 25,1327, in favour of Edward's son, Edward III. Isabella plotted the death of Edward, and had him murdered September 21, 1327 at Berkeley Castle, Gloucester, by having a red-hot spit thrust through his bowels. Isabella and Mortimer shared the Regency until they were overthrown.
Mortimer and his gang were overthrown in 1330 by Edward III, and Mortimer himself was executed. Isabella was forced into "honourable retirement" from public life; she died August 22, 1358. Her tomb was lost during the Reformation.
