An anglicisation of Scottish Gaelic Eóin, the Gaelic equivalent of the name John. The name originated in Ireland, and was taken from there to Scotland, where the modern form Iain co-exists with it. In Ireland it was largely supplanted by the later forms Seaan, Seón, and Seóan, of which the modern form is Seán (anglicised as Sean).

- “If you want a Scotch name why don’t you call him Jock?” Macgregor looked disgusted. “Because Jock is not a name, but a diminutive, as everybody knows well. It is the diminutive of John. And John is not a Scots name. The Scots form of that name is Ian. If you want to call him Ian Fetch, I shall say no more”.
