The term "Scotch-Irish" has led to confusion even among descendants of the Scotch-Irish themselves: some taking it to mean a mixture of Scottish and Irish ethnicities, and others thinking it refers to Irish immigrants to Scotland. The term is also misleading because some of the Scotch-Irish had little or no Scottish ancestry at all,-taken from this page

just to emphasize how I can have the last name scott but not be scottish
