To this, I would add:3. Edward of Angoulême doesn't die of illness at age five, 1370. As a result, the health of his father—Edward, the Black Prince—doesn't collapse utterly. The Black Prince's health still deteriorates over time. He lives on until 1390 or so, dying c. 60 years old (having ruled as Edward IV from 1377 onward). Edward of Angoulême then succeeds him as Edward V, aged 25 and secure in his position. Presumably, he won't have the same problems as his brother Richard (OTL Richard II). The Plantagenet Empire is bolstered, and the Wars of the Roses get averted.
4. Henry V doesn't fall ill, 1422. He inherits the French throne, lives for several more decades, and stabilises Lancastrian rule. When Henry VI finally succeeds to the throne, his father has already destroyed or side-lined the enemies that defeated him in OTL. Henry VI inherits a Plantagenet Empire that has become a complete Anglo-French Union.
5. Richard III wins at Bosworth Field, 1485. Henry Tudor dies. This ends the Wars of the Roses with a definitive Yorkist victory. Soon thereafter, Richard marries Joanna of Portugal, further solidifying his ties to that country through the marriage of Elizabeth of York to the future King Manuel I of Portugal.
1. Harold wins at Hastings and this begins an Anglo-Saxon upheaval.
2. Edward IV lives longer and his elder son Edward V heals the wounds of the War of the Roses.
3. Henry VIII has a male heir from Catherine of Aragon and there's no schism with Rome.
4. Edward VI lives longer and tales England more in the Reformed side while beginning a colonial adventure in the Americas.
