2. Hunting down the coat of arms for a very distant relative doesn't really interest me. I just wondered if there was a book or something that showed clan crests of the past and present.
There are ways to see if there was such a clan, if that clan had a chief and bore arms, and if the crest of the arms was ever used as a "clan badge"; the Scottish Heraldry Society and the Lyon Court would probably be the two best places to start.

Cheers,
