[In the year 737] King Ceolwulf resigned his crown to his cousin Eadbert, to end his days as a monk of Lindisfarne. During Eadbert's reign, Galloway was invaded by a Celtic pretender, Alpyn, son of Echach. The Galwegians rose against him en masse. He conquered the greater part of the country, till he was confronted by Innrechtach, a native chief, near Kelton on the Dee. Here he was completely routed and forced to fly. his retreat was, hoever, carried out in an orderly manner, till, as he was in the act of leaving the province, fording a stream at the entrance of Glen-App, in the midst of his bodyguard, a single man sprang upon him and struck him lifeless from his charger. The stone which marks his sepulture still preserves his name. From time immemorial it has been named in charters as a landmark-- Laight-Alpyn. The pillar-stone itself is the "Laight," whilst Alpyn is still recognisable in the name of the beautiful glen, near which he fell.
The name of Laicht Alpyn really belongs to the farms of Meikle and Little Laicht, on the easter shore of Loch Ryan... On the very line of separation between the two counties is a large upright pillar-stone to which the name of Laicht-Alpin, the monument or grave of Alpin, is actually appropriated.
