for the Scottish song, first installment, I just pasted in the translation as it appears on a site for lyrics of the Sioda album ( a very good collection altogether - I recommend the recording - MacMeanma, Isle of Skye, Scotland). But "Ged gur maighdean mhara mi" - means "although I am a mermaid" not "although you are a mermaid" some say it's the song of the seal maiden who has gone back to the sea, some say it's the song of her deserted lover. Maybe the words of both are represented in different verses - the reference to trickery in the chorus would seem to belong to the human who didn't know his lover was a seal and would have to leave him.
