Gael is the English spelling of the Gaelic word "Gaidheal". This is the name that this noble race called themselves. Words like Scotti , Celti, Kelti etc. were names given to these people by the Greeks and Romans.
Strupag, as you are using a Gaelic nickname I would guess that you are a Gael. Although my family has been on Cape Breton Island for four generations I still consider myself a Gael.
