The Grianal Mermaid of Tiree

Tiree lies in the Inner Hebrides. At its west end is Grianal, the "Sunny Spot", known in English as Greenhill. It appears as Grianal on James Turnbull's map of 1768. Below the farm lies Tràigh Ghrianal, a small rocky beach at the south end of The Maze. At the time, the farm's tacksman, or principal tenant, was Colin MacNiven.

The beginning of harvest, about 1795. Two young girls were walking the Grianal shore. On the beach lay a body, washed up from the sea. Its upper body looked human, the rest like a fish.

The girls fetched MacNiven. The creature was dead. Its arms and hands were human in form, but the fingers were joined by a thin membrane. In MacNiven's sworn words, "its intestines were torn out and the Deponent could not observe where there had been any Sexual distinction".

Retellings add more. The upper half was "like that of a young boy", aged about 12 to 14, "with small flat ears and a short chin". The arms were about 14 inches long, with human fingers and nails, though webbed. Below, it had "fins and a tail which was forked like a mackerel but flat".

MacNiven did not leave it on the shore. The retellings say he and his servants carried it off on a handbarrow, to keep the dogs away. They laid it in "a Grave in a Sand bank near to his the Deponents House". They "raised ane head and foot stone, and threw some loose stones and sand over it". A grave, marked like a person's.

11 August 1813. Tiree House. Some eighteen years after the find, MacNiven swore his account "in the presence of James Maxwell Esquire One of His Majestys Justices of the Peace for the county of Argyll". A physician, Niel Maxwell M.D., also signed. The Tìr Ìseal retelling says the men opened the grave, saw the skeleton and swore in court that this was the body of a mermaid.

The original survives in the Argyll Papers at Inveraray Castle, reference ARG/4/3/65/88. A digitised copy is held at An Iodhlann, transcribed in November 2022 for the Transcribing Tiree Project.

The dates drift, with one retelling setting the find in 1793 and another citing court records from 1812. Nothing explains why the statement came eighteen years late. No known remains survive, and no specimen is recorded anywhere. No source offers an explanation for this case, and none calls it a hoax. The file holds a 2002 letter from Prof. Ian Boyd of St Andrews University, but its contents are not described online.

In 2022 the mermaid reached a new audience. The community arts project Tìr Ìseal nan Òran, built on Turnbull's map, staged "The Tiree Mermaid" on 16 June 2022. Filmmaker Jack Lockhart and pupils of Tiree Primary School flew over that map to Grianal Bay on film. Douglas Roberts brought the deposition into teaching through drama.

Grianal is not alone. On 29 October 1811, at Campbeltown, John M'Isaac gave a sworn account of a mermaid seen at Corphin in Kintyre, in the same county of Argyll. Tiree has its own tradition of a mermaid found at Diobadal. And around 1830, a dead mermaid was buried on Benbecula.
