There will a Clan Scott Gathering June 25-27 hosted by Buccleuch (or at least organized by the Buccleuch Group). (Visits to Clan Scott related locales in the Borders, a welcoming supper on June 24 with Buccleuch, etc.)
Excellent timing, with Bannockburn following on June 28th to 30th. I hope you will be able to attend your Clan Scott gathering and also Bannockburn.
