Cornelius refused to consecrate the Chapel in its roofless state, and it came to only be used for burials. One grave had a carved cover with a roughly worked depiction of an occupant, sleeping; the portion below the waist and wrists is now missing, leading to the 17th/18th century grave slab being popularly re-interpreted as a medieval sheela na gig. The Chapel also contains a Clan Ranald burial recess, dated to 1641; traditionally this is the burial place of Ranald MacDonald of Morar, a famed piper who farmed Sandavore near the end of his life, but he was not even born until 1662.
