Archibald MacGregor, 16th Chief of Clan Gregor1 
He held the position of 16th Chief of the Clan Gregor from.1 In 1691 he was authorised to maintain an armed Highland Watch for the security of Loch Lomond side against ‘broken men.1‘ In 1693 had acquired Craigrostan from Luss but made that territory in 1706 over to the famous Rob Royal MacGregor.1 In June 1693 he took the name of Graham of Kilmanan when the penal laws against Clan Gregor were revived by King William III.1 In 1694 while drunk he shot and killed his ghillie Malcolm MacCurich.1 In 1704 he was one of the Highland chiefs summoned before the Privy Council.1 In July 1714 with him the male line of the usurping 7th Chief came to an end (although other Clan Dugall Ciar cadets continued), and so in (in the hope of collecting the Government pension paid to the Chiefs of Clans to keep quiet) 14 MacGregors descended of the old chiefly house met and chose as the chief Balhaldie, a cadet of Roro.1 He went to Ireland and is said to have been last heard of at a horse-fair in Antrim.1

He was leader of all the most recalcitrant Gregarach of his time, doubtless as ‘righteous heir to The MacGregor.1‘ In 1532 a feud with the MacLarens perhaps arose from MacGregor claims through a MacLaren heiress as their crests are similar and in the Gregarach slew the MacLaren Minister of Balquhidder, claiming the right to share with the MacLarens (descendants of a local Abbot) teh privilege of being the first to enter Balquhidder church on Sundays.1 In 1543 the MacGregors were desperate for land and in Easter Week Duncan led a surprise night attack on peaceful homesteads which, followed by another MacGregor onslaught in 1558, nearly exterminated the Clan Laren and overran their lands in Balquhidder.1 In 1545 he was mentor of the young 8th Chief in the raid that captured Struan Robertson , and in 1548 the Menzies chief inserted a special clause in leases forbidding lands to be sub-let to ‘Duncan MacGregor MacPhadrig’ (Ladasach’s patronymics.)1 He was Tutor of Glenstrae during the 9th Chief’s minority and killed Alasdair Odhar MacGregor of Morenish for acknowledging Campbell of Glenorchy as his chief circa 1550.1 In 1551 he was outlawed for murder and became a noted freebooter, ‘Ardchoille’ becoming the MacGregor slogan (war cry.)1 On 16 June 1552 (an unknown value.)1
