Logan tartan was first recorded in 1831 by the historian James Logan, in his book The Scottish Gaël. Later in 1845 The Clans of the Scottish Highlands was published, which consisted of text from Logan, accompanied by illustrations from R. R. McIan.

Our tartan is shared with Clan MacLennan. Later in 1845,  The Clans of the Scottish Highlands was published, which consisted of text from Logan, accompanied by illustrations from R. R. McIan. This work was the first which showed the MacLennan's sharing the same tartan as the Logans. The text on the history of Clan Logan pointed to an ancient link between the Logans and MacLennans.
 
The plate for MacLennan, shows a man from this clan wearing the Logan tartan, but no name is given to it unlike every other clan tartan shown. Given the style of writing at the time and subtleties used by both the artist and writer, this is not a surprise and allows them to pay homage to the story of the origin of MacLennan.
 
Until the early nineteenth century there was no such thing as "clan tartans". Furthermore, any Clan can adopt any tartan they want. Always remember, any person of any Clan can choose a different tartan. A logan wearing another tartan or other isn't any less a Logan and anybody else wearing our Clan tartan is also honoring us!!!!
