Irish Names

Irish names carry the widest gap on this site between how they look and how they sound, because Irish spelling records a sound system English does not have. Many arrive in two forms: the Irish spelling and an anglicization made by a clerk writing down what he heard. Both are in use, often in the same family, and neither is the wrong one.
