James Logan collected information for his book 'The Scottish Gael' between 1826 and 1831. The MacNaughton tartan is also recorded by W and A Smith in their 'Authenticated Tartans of the Clans and Families of Scotland' (1850). The Tartan Society entry carries on to say 'Other works contain a commonly reproduced error' but doesn't specify what error. The tartan closely resembles the MacDuff, which may bear out the claim that the MacNaughtons were originally a Moray tribe transplanted by Malcolm IV.
