Merrow is the Scottish, Irish & Gaelic equivalent of the mermaid and mermen of other cultures. There are other names pertaining to them in Gaelic: Muir-gheilt, Samhghubha, Muidhuachán, and Suire. They would seem to have been around for millennia because according to the bardic chroniclers, when the Milesians first landed on Irish shores the Suire, or sea-nymphs, played around them on their passage.
