Clarili..sorry if I sounded stroppy .from this side of the pond, the American tendency to throw a lassoo round a lot of wildly different places and label them "Celtic" can feel a littlefunny. And statements like "Irish names Stephens are derived from Mac Giolla Stiofan" need careful consideration before you make them: I mean, unless you actually know that a person had an ncestor of that name, don't say it, because thesethings have, sometimes and unfortunately, wider implications you may not have thought of.It's a very politicised world we live in. Ever heard of Sean macStiofan, for example, and the history of his name?
