There's a Lagganlia, in Alvie parish, neighbour of Rothiemurchus.
Skoosh.
Aittenlia, found it, it's in the valley of the Dulnain, just by the river & between Caggan, a bothy named Eile & Dalnahiatnich.
Caggan was a bothy & Dalnahaitnach a derelict croft. Aittenlia will just be a pile of stones now. Used to know the upper part of that glen well. Divided between several Speyside estates with roads over the hills, north to the Dulnain. Could be Kinrara estate so originally part of the Duke of Gordon's vast territories which were split up & sold off. A very wild place, nobody lives up there, the last wolf in Scotlad was killed therraboots!
PS, there were several "Last Wolves!"
