The Loch Tay area in Perthshire is the origin of a significant branch of Clan Arthur. Bearing a chiefly name, Patrick McArtair was born around 1615 in Killin - The Chiefs of Clan Arthur have historically been named Charles, Duncan, John or Patrick MacArthur, and this Patrick is the ancestor of a branch of Clan Arthur which runs into hundreds of descendants. As yet, the ancestry of Patrick is unknown, but his living descendants include the Clan Arthur Seannachie, Robert McArthur, his son Donald McArthur the High Commissioner for Southern Africa, Frank McArthur the High Commissioner for Britain, and his son Hugh McArthur the Publicity Liaison Officer.
The Loch Tay branch of Clan Arthur represents the oldest known lineage of pure male MacArthur descent and it is possible that a lost Chieftainship is contained within this extensive family. The place name of Tir Artair (Arthur’s Land) near Killin at the head of Loch Tay is recorded is early as 1460 proving that the name was known in the area long before 1615, possibly arriving after the infamous decapitation of John MacArthur in 1427 or even earlier. It is also said that the MacArthurs once held lands in Glen Dochart, though whether that was this particular family of MacArthurs or another is not known at this time.
The family lived on the Breadalbane Estate and around the 1760s the Earl's factor tried to evict Patrick’s great great grandson and his family, but Patrick McArthur (the 2nd) petitioned the Earl to be allowed to stay in his house as he had "an increasing family and an aged mother to look after." The Earl signed across the petition; "Of course he can stay, bearing in mind the service he and his father had given our Cause in the recent troubles." The Earl of Breadalbane was a Jacobite and this proves that this faction of Clan Arthur gave support to the Jacobites at Sherrifmuir in 1715 and Culloden in 1746.
In later history the name of MacArthur was well known on both sides of the Loch and the 1841 Census records 100 MacArthurs in the area spread from Killin to Kenmore - Two of them were 92 years of age.
