The founding tradition · c. 980
The yoke that became a shield
Tradition holds that at the Battle of Luncarty, between the Scots and the Danish invaders, a ploughman named Hay and his two sons — armed with nothing but the yoke of their plough — halted the rout of their countrymen in a narrow pass and turned the tide of battle, saving King Kenneth III.
In gratitude, the king is said to have released a falcon from the summit of Kinnoull Hill, near Perth: all the land the bird overflew would pass to the hero and his line. The falcon crossed the rich lands of the Carse of Gowrie before alighting on a stone thereafter called the “Falcon Stone.”
From this legend proceed the arms of the house — argent, three escutcheons gules, recalling the yokes that became shields — and its motto, Serva Jugum, “keep the yoke.” The falcon remains its crest.
Recorded by the historian Hector Boece (Historia Gentis Scotorum, 1527) and earlier noted by Walter Bower (Scotichronicon, c. 1440). Modern historians regard it as legendary; it remains nonetheless the founding myth of Clan Hay, engraved in its heraldry.
