The attribution, in most libraries, to Richard Lalor Sheils as the author of Sheil's Love Songs (or to Sheil's Shamrock - which has mainly patriotic songs) is not correct. The author was one John Sheil, a weaver, probably from Co Armagh, whose family relocated to Drogheda during or after the 1798 rebellion. I'm currently working on a paper that will associated Sheil (locally pronounced 'Shale") with a range of songs even greater than that in the over twenty volumes of 'Love SOngs' and 'Shamrock'.
