holding lands in Ros Buill (the old kingdom of Ross Guill) now encompassing part of County Donegal.

Under the subheading of "The Part of the Tir Chonaill", that is Conal Gulban's Land (often cited as what is now County Donegal, Ireland) is this entry on page 43, "To MacGillatsamhais the stout Belong Ros-Guill and Ros-Iroguil".

[12] The 17th century genealogy Ane Accompt of the Genealogie of the Campbells traces Colin Mael Maith back to the mythological King Arthur.

According to Alastair Campbell of Airds, a more probable candidate for the ancestor of the clan, rather than the possibly mythological Tàmhas Ceàrr, is the historical Sir Thomas Cambel.

[17] The Manuscript History's content, considering the examination of multiple sources used to produce it, is closer in historical time frame than any other descriptive work, and therefore might be more accurate.

Seannachies would not have omitted someone as important as Thomas Cambel, who swore fealty to Edward I, King of England in the 1296 Ragman Roll.

[21] Historiographer William Skene noted: "The policy of the Argyll family led them to employ every means for the acquisition of property and the extension of the clan.

Though the clan as a whole never seem to have made the slightest sign of adopting the name Campbell, they followed always the breach or banner of the Lords of Lochow in war and all hostings.

[12] Today little of it exists, as it was torn down to make way for the Crinan Canal venture, which also changed the size, shape, and water level of Loch a' Bharain.

Chief Archibald is said to have signed the address welcoming the Pretender, James Stewart, King du jour in Exile.

"The property of those who had joined the rebellion was confiscated, and the 'Forfeited Estates' were administered directly by the government in pursuit of a policy of breaking up the Highlanders' way of life.

The Highlanders were forbidden on pain of death from wearing a tartan plaid (the kilt is the more modern equivalent), bearing arms, or carrying a dirk or dagger".

[43] In 1757, just 10 years after Culloden, Dugald MacTavish is noted as one of the Duke (Archibald Campbell) of Argyll's chamberlains with authority to collect debts.

On 5 November 1785, the Estate of Dunardry was advertised for sale by public auction in December[46] after Lachlan had fallen into financial trouble, partly due to judgment debts against him.

[47][48] At least two decisions by the Court of Session in Edinburgh arose from his father's lead role in failing to account for, and properly executed, the estate of Duncan Campbell of Kilduskland who had died in 1766.

In 1797, three years after work was started on the Crinan Canal, which subsequently divided the estate, Dunardry was purchased by Simon McTavish of Montreal, from Stratherrick, Invernesshire.

[53] Lachlan's son John George McTavish soon became a fur trader with the North West Company under Simon's patronage.

As a result of William not matriculating for the arms, the Chiefly line was considered "lost", or dormant, until 1949, when Lord Lyon, Sir Thomas Innes of Learney, contacted the MacTavish family in Canada, advising them that they were the Chiefly line, inviting them to petition for the Arms and Chiefship of the Clan.

Mrs. MacLoed stumbled onto the connection through her research and wrote to the Lord Lyon King of Arms,[55] who in turn had contacted the MacTavish family in Canada in 1950, advising them of the heir-ship and urging J.W.

was informed from his service in World War I, living on a small government pension, and did not matriculate, even though Lord Lyon reached out to J.W.

[60] The clan name MacTavish is an Anglicised form of the Gaelic MacTàmhais,[61] which translates to Thomson or Thom(p)son in English.

Some spellings found within old Scottish charters, post-Culloden parish registers, and in "The Commons Argyll" appear as MacAvis, MacCamis, McCawis,McKavis, McKnavis, M'Ash, MacAnish, mcTais, MacTavifh and mcThavish, to give a few.

In 1793, John Hooke-Campbell, Lord Lyon King of Arms, granted the following coat of arms to Lachlan MacTavish of Dunardry: Quarterly, 1st and 4th a Gyronny of eight Sable and Or; 2nd and 3rd, Argent, a buck's head cabossed Gules attired Or on a chief engrailed Azure a cross crosslet fitchèe between two mullets Or.
