Traditional Irish Boys’ Names: D-I
The Story of a Name: Fionn

The Salmon of Knowledge
The legend of Fionn McCumhaill, or Finn Mc Cool, is probably the most famous of all Irish Legends. There are many stories told about him, but my favourite is the tale of how he acquired his great knowledge.
As a boy he was sent to study with the druid and poet Finnegas, who for seven years had been obsessed with a quest to catch a salmon.
Not just any salmon, this one had eaten the hazel nuts that fell from nine trees surrounding a well and in so doing become possessed of all the knowledge in the world.
The first person who could eat of this salmon’s flesh would in turn have this knowledge.
Eventually he caught the fish and instructed Fionn to cook it. While doing so the boy burned his thumb and without thinking stuck it into his mouth, in so doing putting a piece of the fish’s skin in his mouth also. And so it was he and not his master who was endowed with the gift of all pervading knowledge.

I called my son Eoghan. I have been told by a friend of mine who is a professor of Celtic studies, that it is not the Irish for john but actually dates back to the pre-christian era.
I think you are probably correct. Irish to English is not always a direct translation when it comes to names.
Eoghan is actually a Scottish name, Scotts Gaelic and Irish (gaeilge) are very similar. Sean is the Irish for John and Eoghan is the Scotts Gaelic for John. The two languages are connected in many ways and this may be why Eoghan is often classified as Irish!

Fantastic information. Thanks! Diarmuid reminds me of druid. Perhaps someday I’ll have a great white beard and live in a tree. Suits me.
Dont agree at all….Eoghan or Eoin does indeed have Irish roots. Just becasue it also has scottish roots does not make it less irish.
