There is a confounding here -

There is a song, THE QUEEN OF HEARTS, which is of Scottish origin, and relates to the marriage of Elizabeth, who was the elder sister of James I of England, and a very nice person, to the ELector of Hanover, who was a complete pillock save for the fact that Elizabeth loved him dearly. The Queen of hearts does not come with the chorus - Martin Carthy did a very nice version - I know my love is later, Irish, and sets the same events into a more common surrounding. While I know my love is more commonly known, much of the sentiment and meaning (Jacobite in nature) is lost in it
