This person is not mentioned in Burke's Peerage, which has Gillemichael a son of "Edelrad, apparently Earl of Fife, who flourished in the early 12th century and was also Abbot of Dunkeld; possibly the same person as Eth who fathered Gillemichael". Heth Aethelred is probably the Edelrad and Eth mentioned by Burke's Peerage. However several internet lines have Duffagan or Duff between Eth and Gillemichael and would explain the "MacDuff" name of subsequent generations.
