A late legendary genealogy of the Stewarts (found in a genealogical work published by David Symson during the reign of Queen Anne, and later summarised in the old published genealogy of the Stewarts of Appin) claims that the Stewarts' alleged ancestor Banquho, Thane of Lochaber, was the son of a suppositious Kenneth, Thane of Lochaber.
As was proven by Horace Round a couple centuries ago, neither Banquho nor his purported father Kenneth ever existed. There were never any Thanes of Lochaber, and the Stewarts were in fact a Breton family that served as stewards to the Lord of Dol in Brittany.
In my own research on the Banquho question, I have proposed, or wondered, that "Banquho" may have been a garbled memory of Hamon, Lord of Dol, who may have been the father of the first Flaald, steward of Dol. Flaald was later garbled in Renaissance Scottish legend (first attested in Hector Boece's Chronicle of Scotland) to become "Fleanchus" or Fleance, son of Banquho. Maybe "Fleance, son of Banquho," is a confused memory of "Flaald, son of Hamon." Maybe. Flaald's father is not proven, and the equation of Banquho with Hamon is only a guess of mine.
