Àth nam Athfhinn
Àth nam Athfhinn is a ford through Uisge Athfhinn where the track of Làirig Laoigh crosses the river.
As a place name Àth nam Athfhinn - means ford of very bright one.
Àth nam Athfhinn is a place name whose non-obvious derivation disappears into the mist of time. Some earlier writers cleverly write ''There is a tradition ...'' before retelling a story, or explaining a derivation to avoid getting into a discussion about the truth of the story, or derivation. I say cleverly because these stories, and derivations are worth keeping alive whether or not they are true - any discussion about their truth is pointless.
In Gordon (1925) the author gives us the 'tradition' of the derivation - writing :
Fionn was out hunting on the hill. His wife was with him, and when he crossed the A'an and she attempted to follow him the violence of the stream swept her off her feet and she was carried away and drowned. Fionn, with sorrow heavy upon him, said :
''Chaidh mo bhean-sa bhàthadh
Air Uisge Bàn nan clachan sleamhuinn ;
'S bho chaidh mo bhean a bhàtadh,
Bheirmid Athfhinn air an abhuinn.''
''My wife has been drowned on the Fair Water of the slippery stones ; and since my wife has been drowned, let us call the river Athfhinn.''
- Gordon 1925 (p54)
That's the 'tradition' associated with the name of the river ; the river gives its name to the ford, the loch, and the hill.
