The trouble with such anecdotes, of course, is that most of the time they are created well after the fact and often are demonstrably incorrect. For example:
There is an oft-told story that in 1050 the chief of the Cunningham family of England traveled to Scotland where he aided Prince Malcolm, son of King Duncan who had been killed by MacBeth in 1040. MacBeth also pursued Prince Malcolm and Malcolm was hidden by the Cunningham chief in a barn under some hay. (Another version of the story has Cunningham and his sons out working in a hayfield when Malcolm passed by, MacBeth’s men hot on his trail. They hid Malcolm under some hay in the field, with Cunningham ordering his sons to "Over. Fork over" the hay to cover the future king, thus also leading to the adoption of the Cunningham motto: Over fork over.) MacBeth was later defeated by Prince Malcolm at the Battle of Dunismore near Perth in 1057. When Malcolm became King Malcolm III of Scotland, he rewarded the Cunninghams with a coat of arms consisting of a black hayfork (heraldically, a shakefork) centered on a silver shield.
