Hi Skoosh, i have only just noticed your comment. Urray was a great help thanks. I have found much more info on my Cowans after looking into the Glasgow poor relief records. I think you're correct, Maggie did live and work in Strathpeffer. My great uncle gave me a copy of a photo he said is Catherine Grant, Mary Cowan, and an unknown boy outside the cottage in Orrinside.
That's really great to see the plans for Fairburn Tower. It'll be interesting to see it restored.
Cheers,
Alasdair
