Birth of Richard, oldest son of Richard Nevill & Alice Montacute, earl and countess of Salisbury.
As this date is St Cecelia’s day, it is not beyond the bounds of possibility that Richard’s sister Cecily (who shared a wedding date with him) could have been his twin.
Death of Alice Fitzhugh, widow of lord Henry Fitzhugh. Alice was the third daughter and fifth child of the earl and countess of Salisbury.
Alice’s sister, Katheryn Nevill, widow of William Bonville lord Harrington and William lord Hastings also died in this year, some time before this date.
