Thanks Grizzly,
I appreciate the link and your reminder about blurry lines and skirmishes. I am staying in Pitlochry for a couple of days and want to get a feel for the land. I will be in Bruar and maybe Dunkeld. I also hope to see loch Tummel and Queens View. I am not sure if the Tay is part of the Robertson territory although I have seen some articles about the significance of the Dunkeld cathedral in Robertson history as well as references to St. Columba.
