Hi there, very interested to hear what gorski had to say.....
I have an ancestor, Hector Mackenzie who was a tenant at Arrielettrach (on the south shore of Loch Luichart), probably before 1700 who had a son Roderick who had a son Thomas who had a son Roderick who married Mary McLean about 1780 and from whose son Thomas born 1786 in Fodderty I am descended.
Is it possible that gorski's "Avire Letterlach" is a garbled version of the farm name?
There is a Glastullich in Easter Ross as well as the one near Ullapool

Her father was Thomas Joesph Mackenzie born 3rd January 1866 Ullapool brother Peter Alexander Mackenzie. They being the sons of Peter Mackenzie who had a brother Kenneth, sons of Thomas Mackenzie who married Magdalene More?. Thomas had a brother Kenneth (farmer Glastullech) who were the sons of Hector Mackenzie and Avire Letterlach who according to notes that I have have are linked to a Roderick, Alexander and Colin. Thomas Mackenzie was school master Shore Street, Ullapool in 1840. Are there any links to your Mackenzie's?"
