MacCulloch Tartans
The MacCullochs of Ross-shire, as septs of the Clan Munro and Clan Ross, are permitted to wear either of those clans' tartans and the MacCullochs of Oban, as septs of the Clan MacDougall, may wear their tartan or even the District of Galloway tartan. However the MacCullochs themselves also have their own clan tartan as well as a second "dress" tartan.
