Hi there; I know some folks in Boston who have named their boat this same thing. Your spelling looks close enough to what they use. I have a book at home with a glossary of Celtic myth figures in it; I will look up the spelling if you wanna be more exact. Don't forget Grianne (pronounced GREE-un; slight roll of r sound); who was a solar goddess (not to be confused with Grainne, a version of the Arthurian Igraine). Honoring the sun while on a boat is not such a bad idea! peg
