Another Mackintosh clansmen was John Malcolmson who was the natural son of chief Lachlan's deceased elder half-brother. Lachlan appears to have been extremely kind towards him; in 1522 he gave to him the occupation of Connage in Petty and marriage to Effie Dunbar, relic of
Andrew Munro of Milntown. However, on 25 March 1524, John Malcolmson, along with two
Davidsons and some accomplices treacherously murdered chief Lachlan Beg Mackintosh when he was hunting at Ravoch,
Badenoch. The murderers took refuge in the fort at Loch-an-Eilan (Rothiemurchus). However, there they were captured three months later by Donald Glas, natural son of Lachlan's predecessor, along with Donald MacWilliam the grandson of Alan and aided by the chief of
Clan Gregor who had married a sister of the deceased Lachlan. The murderers, John Malcolmson and his two principal assistants, were tried and found guilty by the Earl of Moray. Malcolmson was beheaded and
quartered and the two Davidsons were
tortured and then
hanged. However, other accounts of this episode make no mention of their trial by the Earl of Moray and only that they were cut to pieces upon being captured. ==Family==
