MACTAVISH is the modern spelling of this clan’s name. Originally it had many forms, chief of which were Thompson, Thomason, MacOmish and MacCombie derived from MacTommie, and MacThamais or MacTavish, from the Scots Tammas. In Perthshire, as early as 1488, Donald MacCause (another form of the name) obtained lands near Killin, where he died in 1491. Many of the Argyllshire MacTavishes have changed their name to Thompson. This family claim to be a sept of the Clan Campbell, descended from a son of Colin, the third Campbell, from whom are descended Clan Tavish Campbell. MacTavish of Dunardy was Chief of the clan.
THIS is a Celtic clan. Their country was the western shore of Loch Lomond. They took their war cry from Loch Sloy, at the foot of Ben Voirlich. They are descended from Duncan MacGilchrist, mentioned 1296, brother of Mulduin, Earl of Lennox. His grandson was Bartholomew (Gaelic, Parlan), from whom the clan is named. Malcolm received the lands of Arrochar in 1395, but the male line failed, and the lands were forfeited. Andrew MacFarlane married a daughter of the Earl of Lennox, and succeeded in 1493. Sir John MacFarlane fell at Flodden, and Walter MacFarlane of Tarbert was killed at Pinkie in 1547. The clan fought against Queen Mary at Langside. In 1608 they slew Colquhoun of Luss, and were outlawed. In 1644-45 they fought for Montrose. Major-General MacFarlane gallantly captured Ischia, in the Bay of Naples, in 1809. In 1624 many of the clan settled in Aberdeenshire under other names. The last Chief is supposed to have gone to America at the end of the eighteenth century. His house of Arrochar became the property of the Duke of Argyll.
