Eoil na Máirbhdhine

Eoil na Máirbhdhine is a small island off the coast of the island of Rockall in the Seafaring Confederation and the smallest and westernmost of the islands of An Oilíana hÓ Dhéase in the viscountcy of An Uinnia. Due to its incorrect placement on mediaeval maps it is often thought of as the southernmost island of the Rockallic archipelago, however, this is incorrect. The actual southernmost island is Tóinn Dhúibh.

The island is also its own baronetcy. In 2014, the baronetcy had 47 inhabitants, the lowest number of inhabitants of any baronetcy in the country.
