Ian

From Wikipedia, the free encyclopedia.

Ian is an anglicisation of Eóin, the gaelic form 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).
