I always understood "planxty" to apply to a tune written about a male,whereas a "pleraca" was written in honour of a woman ?? Thus I always introduce "Pleraca Fanni Ni Poer" when I play "Fanny Power" as such. PS I believe that the eponymous lady was "fancied" by Carolan, who was invited to her wedding but failed to impress her with his musical artistry !
