Exept for some Porters in Dublin this name in Ireland is exclusive to Ulster.  It is most common in counties Antrim, Down, Derry and Armagh.  It can be of English or Scottish origin.

Porter is an occupational name and though it can derive from the Old French porteur, meaning a 'carrier of burdens', its main derivation is from the Old French portier, a 'porter' or 'doorkeeper'.  In medieval times the office of porter was one of the most important in castle and monastery and came with lands and privileges.  The word was in Scotland gaelicised as portair, which had the extra meaning of 'ferryman'.

The name is one of the most common in every kind of Irish record since the thirteenth century, but most in Ulster will be of post-Plantation origin.  The most famous of the name in Ulster was a Presbyterian minister, the Revd James Porter, 1753-98, of Greyabbey, Co. Down.  He was a United Irishman and a series of letters he published under the title Billy Bluff and Squire Firebrand drew the attention of the government.  He was tried on the false evidence of an informer and hanged at Greyabbey within sight of his home and church.
