Morris at Heathfield has certainly done his homework. At least it shows that a once feared clan has translated the energy once used to hatch nefarious plans against its neighbours, into internal tartan politics.

Along with the other Whig clans of the mid-1700s, Clan Campbell filled the ranks of the government highland regiments that both policed the highlands and fought the House of Hanover's battles against the French, at high cost. In a generation, gentlemen from Jacobite clans joined them.
If there ever was a Campbell "family" regiment, it was the Argyll and Sutherland Highlanders, rather than the Black Watch.

Finally, I'm beginning to think that diced hose might be the right choice at this point.
