Doc, the Douglas tartan is associated with the Cameronians(Scottish Rifles), the men wore trews of Douglas tartan and the pipers kilts. Sadly they were disbanded in 1968.
I bet Episcopal can post info concerning other regiments that also wore the Douglas tartan.
Glad to hear your finally kilted brother 8) Enjoy your new lease on life.
