A peasant named Hay and his two strapping great sons were ploughing a nearby field. When Hay saw the invaders, he and his two sons (who were known to love a ruck) ran to fight, encouraging others to follow. The effect was for the weary invaders to retreat believing a new army was about to hit them- Big Jessies!
King Kenneth rewarded Hay with a dram fuelled ceilidh in his castle at Perth and a gift of land. Hay decided on some land around Errol. King Ken, who was a keen falconer, and obviously still quite drunk, determined the boundaries by flight of falcon. The falcon flew through the Carse and landed on a large stone near St Madoes, which to this day is called Hawkstane, and remains some 1000 years later, at the boundary of the estate.
The falcon’s journey is thus described: “The falcon flew to ane toun IV miles from Dundee called Rosse and alighted on ane stane which is called The Falcon Stane and so he got all the lands betwixt Tay and Arole six miles of length and four of breadth which lands are still inhabited by his posteritie”.
