I just thought I would mention that I have donated copies of my Key issues for a Clan Gunn history to the Orkney Islands library service - a copy is meant to be available from the Kirkwall library and the other will be at Stromness library. For other places of public access of the text see http://clangunn.weebly.com/clan-gunn-blog/key-issues-for-a-clan-gunn-history-access
The Orkney islands were a great place to go for a holiday - the neollithic archaeology was wonderful (it's a UNESCO World Heritage Site) and this includes Skara Brae, Maes Howe, the Ring of Brodgar, Stenness standing stones, the Broch of Gurness and much more. There was also good Viking history and we had a great trip around Scapa Distillery (near Kirkwall) which has excellent whisky. A visit to Hoy island was important to understand the Orkney islands in both World Wars (Scapa Flow and all that) and seeing the 'Old Man of Hoy' was of real interest. We also visited Rousay island for more great archaeology. I could go on but you get the idea of how fascinating these islands are...
Just a shame the Clan Gunn does not originate from the Orkney islands...
