14. Margaret Courtenay married (1) John Champernoun
Remarks : The implication is that the Plantagenet ancestry came to the Champernouns via Margaret Courtenay, since no earlier Plantagenet ancestry is indicated for Sir John Champernoun. However, elsewhere in PA (page 126) is listed Isabel Bonville (descendant of Henry II) who married Richard Champernoun. I believe there is a connection between this couple and Sir John Champernoun, as follows
Isabel Bonville, m.Richard Champernoun
Hugh Champernoun, m.Alice Bois
William Champernoun, m.Elizabeth Chuderlegh (or Chidderleigh)
Sir John Champernoun, m. Margaret Courtenay
