The motto of the MacGregors is, Een do and spair nocht, said to have been given them in the twelfth century by the king of Scotland. While the king was hunting he was attacked by a wild boar, when Sir Malcolm requested permission to encounter the creature. Een do, said the king, and spair nocht. Whereupon the strong baronet tore up an oak sappling and despatched the enraged animal. For this defence the king gave Sir Malcolm permission to use the said motto, and, in place of a Scotch fir, to adopt for crest an oak-tree eradicate, proper.
Another motto of the MacGregors isSriogal mo dhream.
