I note that whilst Lulie is a MacAlister she wears a form of Maxwell tartan.
On the book-cover?
Well spotted Bob, it is more like Maxwell. I was happy enough with it (Madiosi's lovely creation),
as Maxwell is actually more local in my Northern Forest than MacAlister,
and the MacAlister sett is pretty similar:
I love your creation of a light-background 'dress Maxwell', as you say, there isn't one on the Register,
here's dress MacAlister, which was the kind of style I had in mind when I mentioned the white background:
There is indeed the official Register of Tartans maintained by Scottish National Records,
in case anyone else is interested it's at:
https://www.tartanregister.gov.uk/index.aspx
If you happen to have a Scottish surname, you can wear the appropriate tartan at any gathering,
and no-one will mind. And any other Scottish connections may well give you one too -
links with a region, a regiment, a university, etc., and 'general purpose' ones anyone can wear,
or you can even register a personal one. But there is, as you say, no copyright
(except perhaps to personal or company ones),
it's just a bit of a faux pas to wear a tartan you're not really entitled to.
Clan crests, too, can be worn as a badge by anyone with the clan surname, e.g Maxwell:
But a coat of arms is a different matter, a coat of arms is the private property of an individual,
there is no such thing as a 'family coat of arms', don't be fooled by all the websites selling these to the gullible,
e.g. these are the arms of William St John Somerville McAlester of Loup and Kennox,
Chief of the Name and Arms of MacAlister (I've shown these as there isn't a holder of the Chief's arms of Maxwell at present).
If anyone else were to use those arms publicly in Scotland, they would be committing an offence,
and would receive a stern warning from the Lord Lyon King of Arms, who, if ignored, can impose a hefty fine,
or maybe even lock you in the jougs (see Lassie-Hunting story
).
A certain Aberdeenshire business owner came up against that fearsome figure not long ago,
And he had no choice but to submit a humble petition for a proper grant of arms
I see he is reported to have commissioned a tartan design for his golf courses,
but the only Trump tartan on the Register is a personal one in his daughter's name, Ivanka:
