Blair


In Ireland very few of Blairs live outside Ulster where over half are from Co. Antrim and most of the remainder from counties Derry and Tyrone.  It is a Scottish name, common here since the Plantation.  It is territorial in origin taken from any one of a number of places in Scotland so named.  The placename itself derives from the Gaelic blar, meaning 'plain', 'field' or 'battlefield'.
