In August 1928 Mr. W. Cubbon and Mr. J. R. Bruce, at the request of the Manx Museum, examined a mound about a mile west-north-west of the town of Ramsey. This had been raised on a gravel bank at the eastern end of what was formerly Loch Mallow. Though inconspicuous, it had long been known, and as early as the thirteenth century was noted as a landmark between the Lord's lands and the Abbey lands in the parish of Lezayre, being referred to by name as Leabba AuKonalhay, i. e. grave of O'Conoly.
