Maclachlan, or Maclauchlan, is the name of another clan classified by Skene as belonging to the great race of the Siol Conn, and in the MS., so much valued by this writer, of 1450, the Maclachlans are traced to Gilchrist, a grandson of that Anradan or Henry, from whom all the clans of the Siol Gillevray are said to be descended. They possessed the barony of Strathlachlan in Cowal, and other extensive possessions in the parishes of Glassrie and Kilmartin, and on Loch Awe side, which were separated from the main seat of the family by Loch Fyne.
They were one of those Gaelic tribes who adopted the oared galley for their special device, as indicative of their connection, either by residence or descent, with the Isles. An ancestor of the family, Lachlan Mor, who lived in the 13th century, is described in the Gaelic MS. of 1450, as “son of Patrick, son of Gilchrist, son of De dalan, called the clumsy, son of Anradan, from whom are descended also the clan Neill.”
MACLACHLAN.
By tradition the Maclachlans are said to have come from Ireland, their original stock being the O’Loughlins of Meath.
According to the Irish genealogies, the clan Lachlan, the Lamonds, and the MacEwens of Otter, were kindred tribes, being descended from brothers who were sons of De dalan above referred to, and tradition relates that they took possession of the greater part of the district of Cowal, from Toward Point to Strachur at the same time; the Lamonds being separated from the MacEwens by the river of Kilfinan, and the MacEwens from the Maclachlans by the stream which separates the parishes of Kilfinan and Strath Lachlan. De dalan, the common ancestor of these families, is stated in ancient Irish genealogies to have been the grandson of Hugh Atlaman, the head of the great family of O’Neils, kings of Ireland.
About 1230, Gilchrist Maclachlan, who is mentioned in the manuscript of 1450 as chief of the family of Maclachlan at the time, is a witness to a charter of Kilfinan granted by Laumanus, ancestor of the Lamonds.
