Baroness Isabell or Elizabeth Stafford - Death Date

I would suggest that 3 May 1405 for Elizabeth Stafford's death is wrong. Her husband John Tuchet died in 19 Dec 1408 and Douglas Richardson notes that "In 1409 the King requested that his widow's brother, Humphrey Stafford the younger, deliver her son and heir to his custody", 'his widow' being Elizabeth.
Richardson goes on to say "In 1436 Thomas Stawell sued Elizabeth, late the wife of John Tuchet, Knt., her son, James Tuchet, Knt., her brother, John Stafford, Bishop of Bath and Wells, and William Lee for the manors of Nether Stowey".
The suggestion is, therefore, that she was alive and well in 1409 and again in 1436.
