Among the illegitimate cadet branches of the House of Forbes, the first to be noted must be undoubtedly the three natural sons of Sir John Forbes of the Black Lip, a given by Matthew Lumsden:

They were:


and John.

Duncan was designated as “Evil Duncan of Auchintoul, and obtained these lands from a brother of the Earl of Mar, and possessed them for a long time,

died without having a legitimate son — only two daughters:

one of whom, according to Lumsden, married Calder of Haughton, and
the other, a Raitt of Hallgrenn.

He left a bastard son named Thomas, married ane gentlewoman called Christian Fraser, and got on her ane good man, who has been stout in that house, called George Forbes, who had seven or eight sons, whose succession works I will not tire me to writt.” (Lumsden)
