I just did a quick search in the Scottish Register of Tartans, and noted that the three Lendrum tartans listed are all variants of the MacFarlane tartan, and one is associated with the "nefarious" Sobieski Stewarts. The notes for the "Lyon version" of the Lendrum tartan states:

D.C. Stewart believed this sett to be considerably older than the 'recorded' date given here. There is no obvious connection between MacFarlane and Lendrum despite extensive research. MacFarlanes originally lived in the lands about Arrochar. Lendrum has been associated with Aberdeenshire. This design is recorded with the Lord Lyon 1957.

More to follow, I'm sure...

Courage!
