12.John Sutton. He married before 10 December 1401 Constance Blount. On page 278 is displayed that their son and heir, John Sutton (or Dudley) was born 25 December 1400, and baptised at Barton-under-Needwood, Derbyshire.
Remark : To be their son _and heir_ he has to be born legitimately. This should make the marriage date at least _before 25 December 1400_ about a year before the precise date given by Richardson.
