It is estimated that people first settled in Rosmuc in AD 400, one hundred years before Naomh Briocán brought Christianity to the area. It is believed that the name 'Ros Muc' comes from the old Irish "the peninsula of rounded hills", ros meaning "promontory | headland" and muc meaning "rounded hills" or "pig" as in the rounded hills on the horizon surrounding the district look like the rounded backs of farm animals. The Irish word for peninsula is leithinis and seems to have a slightly different connotation than the meaning of ros.
