Sorry, my scanner seems to have packed up, so here is a transcript of the relevant passage that was asked for.
Page 102, North Uist in History and Legend, by Bill Lawson:
"Donald MacKinnon, who was cleared from Loch Portain to Baleshare gave evidence to the Royal Commission in 1894 which is summarised here.
"There were townships formerly on the north side of Loch Eport, at Cainish. There were seven crofters at Cainish; the late Dr MacLeod had the other part of the land, and he had a shepherd at Brenish, who was at that time attached to the farm of Balelone on the west side. The crofters were removed from Cainish fully 55 years ago. I distinctly remember them being there. I would think that about a score of crofters could be settled on the north side of Loch Eport, keeping in view the extent of the land they formerly occupied."
As I said earlier, Brenish does not come up in the index but does appear on this page, so there may be other references I haven't found. It's a fascinating book and I can recommend a purchase.
I think that's about all I can help you with at my end, but good luck in your research.
