C.H. Cowley undertook an excavation on 24 July 1921 and opened two graves thought to be part of an early medieval cemetery associated with a lost keeill. One of the graves was built of shore stones, the other with slate slabs. Pebbles were found in the graves but no bones survived. On 12 November 1922 Cowley also found the base of a flint "sickle stone."
