Edmund Beaufort
As such, the character of Montague seems to represent two separate historical personages in the play, and whilst this is not unusual in Shakespearean histories, the manner of the dual representation is. For example, in "1 Henry VI" and "2 Henry VI", the character of Somerset represents both John Beaufort, 1st Duke of Somerset and his younger brother, Edmund Beaufort, 2nd Duke of Somerset. Similarly, in "3 Henry VI", another character called Somerset represents both Henry Beaufort, 3rd Duke of Somerset and his younger brother Edmund Beaufort, 4th Duke of Somerset. However, both Somerset in "1 Henry VI" and "2 Henry VI" and Somerset in "3 Henry VI" are presented as consistent characters "within" the play, i.e. Somerset in "1 Henry VI" and "2 Henry VI" does not represent John Beaufort sometimes and Edmund Beaufort at others; he is consistently the "same" character in the "milieu" of the play. The same is true of Somerset in "3 Henry VI"; "as a character", he is always the same person.
