Clan Colquhoun is an old clan in Scotland. Three chiefs from their clan are buried in Luss Parish Church graveyard in the town of Luss off the shores of Loch Lomond. Their graves are sitting up against a tree and are recognised from a distance as the words "CNOC ELACHAN" are marked in red. The wife of one clan chief is also buried beside them.
The words "Cnoc Elachen" are the Scottish-Gaelic words for "Clan Colquhoun".
