‡ General
  • Duff Genealogy, with material largely taken from "The Book of the Duffs" by Alexander ("Alistair") & Hettie Tayler, gives no birth or death dates for the ancestral line going up six generations to the Duncan who is stated to have married a daughter or niece of the presumed childless King Malcolm IV of Scotland, nor any birth dates for earlier generations leading up to King Duff of Scotland (-967). Average generation length is 30 to 35 years back to the king.

Presumably John predeceased his father, because brother David became the 12th Earl of Athole. Alternatively, David was older.

Ω Birth
  • Birth probably around 1335 - 1340.
