On 28 May 1444 the Treaty of Tours was concluded. The terms included the marriage of King Henry VI of England and II of France (age 22) and Margaret of Anjou (age 14) in return for which England ceded the strategically important French County of Maine to France; she brought no dowry. The Treaty was negotiated by William de la Pole Duke of Suffolk (age 47). The cessation of Maine subsequently came as something of surprise to Edmund Beaufort Earl Somerset (age 38) who was its Governor. He, Somerset (age 38), was offered the Governorship of Normandy instead leading to a further rift between Somerset (age 38) and Richard Duke of York (age 32) who had already been offered Normandy. These seeds of the Wars of the Roses were falling on fertile ground.
On 30 May 1444 [his brother] John Beaufort 1st Duke Somerset (age 41) committed suicide. Suicide not certain but likely. Duke Somerset, Earl Kendal extinct.

On 23 Feb 1447 Humphrey Lancaster 1st Duke Gloucester (age 56) died at Bury St Edmunds, Suffolk [Map]. He was possibly poisoned although more likely he died from a stroke. He was buried at St Alban's Cathedral [Map]. Duke Gloucester, Earl Pembroke extinct. His death left England with no heir to the throne in a direct line. Richard Plantagenet 3rd Duke York (age 35) became heir presumptive until the birth of Edward of Westinster Prince of Wales six years later.
On 03 Jan 1448 Anne Beauchamp 15th Countess Warwick (age 4) died at Ewelme, Oxfordshire aged four whilst in the care of Alice Chaucer Duchess Suffolk (age 44).

Anne Beauchamp (age 21) succeeded 16th Countess Warwick. Her husband Richard Neville (age 19) by marriage Earl Warwick; the first step on his journey to becoming Kingmaker.
The decision of the court was not subscribed to by Edmund Beaufort Earl Somerset (age 42) who was married to Anne's (age 21) half-sister Eleanor (age 39); he wanted his share of the considerable Beauchamp inheritance.
On 31 Mar 1448 Edmund Beaufort 1st or 2nd Duke Somerset (age 42) was created 1st Duke Somerset. He is frequently referred to as the 2nd Duke Somerset since his brother [his brother] John Beaufort 1st Duke Somerset was the 1st Duke Somerset of the first creation. Edmund didn't inherit the Dukedom from his brother; it was a new creation. His did inherit the Earldom.

Edmund Beaufort 1st or 2nd Duke Somerset (age 47) was suggested at the time.
