Well... my tartan is a little interesting:
Cooper/Couper - Loyalist/Protestant:

Ancient is the same with some orange/yellow added in the thinner verticle bands between the white verticle lines.
Made by members that joined the Orange Order, in order to have a 'Protestant' kilt, instead of the one associated with the Couper's that fought for the Stewart's, and on the side of the Catholic Church during the Bishop's War.
But enough about them, onto the 'proper' tartans that I wear
Cooper/Couper - Catholic/Jacobite 'Modern'
Cooper/Couper - Catholic/Jacobute 'Ancient'
As you can see even the tartans in my family tell a little story - or at least show who sided with who during '45.
