 The name Dunderave is of Gaelic origin.Since the MacNachtans were designated 'of Dunderave' from as early as 1473, the place-name appears to have moved with the clan from the Dubh Loch.It has been suggested that the name derives either from Dun-an-Rudha, meaning 'The Knoll on the Promontory', or else from Dun-da-Ramh, 'The Castle of Two Oars'.
