Inis Sionnaigh

Inis Sionnaigh is a small islet in County Donegal, Ireland. The name suggests a connection to a fox, though no further detail survives in the provided facts. A place small enough to hide in a bay yet distinct enough to keep its own identity may have served as a marker, a refuge or a forgotten boundary. The sea around Donegal still changes the shape of small lands, so the islet may have grown, shrunk or disappeared and returned under different names.
