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).
