Tiryny in Athole are made cadets of the Macintosh, but we know that they were in reality derived from the thanes of Struan and of Glentilt respectively, and we must likewise look elsewhere for the thane from whom the old Macintoshes of Badenoch descended. Now we find that in 1170 King William the Lion grants the lands of Brass, now Birse, in Deeside, to the bishops of Aberdeen, ‘his thaynes being however excepted,’ that is, retaining their lands as thanes. In 1226 King Alexander the Second grants to the bishop of Moray the lands of Rathmorcus or Rothymurchus to be held in free forest; and in 1241 to the bishop of Aberdeen the right to hold his lands of Brass or Birse in free forest.[491] These grants in free forest would exclude the thanes of their lands, but we find in 1382 a precept by King Robert the Second directed to his son Alexander Stewart, Lord of Badenoch, requiring him to restrain Farchard MacToschy and his adherents from disturbing the bishop of Aberdeen and his tenants in the lands of Brass, and to oblige him to prosecute his claim by form of law.[492] This Farchard appears in the genealogy of the old MacIntoshes at the time, and the Lord of Badenoch must have been regarded as his overlord. The tradition of the MacIntoshes is that Rothiemurchus was their earliest possession, and when Alexander MacIntosh obtains a feudal right to the lands in 1464 he is termed thane of Rothymurchus.[493] It seems probable that the name was derived from the thanes of Brass, who may also have been thanes of Rothiemurchus, and from whom the old MacIntoshes were descended. In their genealogy the name of _Gillemichael_, or the servant of St. Michael, appears in place of the spurious Angus, the supposititious husband of Eva, and St. Michael was the patron saint of the parish of Birse.[494] As possessors of Rothiemurchus they are brought into immediate contact with that branch of the old Clan Chattan whose principal seat was Dalnavert, and no doubt were, as indicated in the older genealogies, a branch of that clan. The representatives of these older MacIntoshes were, beyond doubt, the Shaws of Rothiemurchus and the Farquharsons of Strathdee, who extended from Badenoch as far as Birse, and whose head in 1464 was Alexander Keir MacIntosh.
