Clan Galbraith is one of the few (if not the only) Scottish clans that has no sticker. Their tartan (badge, coat of arms, history and the like, too) is identified on the Wikipedia page: https://en.wikipedia.org/wiki/Clan_Galbraith - Note also that a Clan Galbraith Association was established in the US in 1980, and is affiliated with the Council of Scottish Clans and Associations https://www.clangalbraith.org/
And finally, that they are conducting a DNA project and screening for a possible Clan Chief appointee.
Thanks! Alan 26th great-grandson of the 1st Clan Chief Galbraith
