I have recent discovered the music of Loreena McKennitt.
She has a song called “The Bonny Swans”, which she says is adapted from a fable “in which a girl, drowned by her jealous sister, returns first as a swan and then is transformed into a harp”
The closing lyrics to the song sound like they could be a historical reference:
“And there does sit my father the King…”
“And yonder sits my mother the Queen…”
“And there does sit my brother Hugh…”
“And by him William, sweet and true…”
“And there does sit my false sister Anne…”
“Who drowned me for the sake of a man…”
It seems to describe a princess with a brother named Hugh, a sister named Anne, and a sweetheart named William, who perhaps ended up with Anne.
Does anyone have an idea of what this might be ref to, if it is at all?
