Joyce acquired the antiquarian source of Professor Richard Jenkins. Who's sum total of My Jewel My Joy was a few lines of verse only by Mr. Aldwell of cork. Who heard air of the song about the year 1790. My Jewel My Joy was originally sent to Professor Richard Jenkins assumedly in a letter around Dec. 17, 1848,and then Joyce puts in print The mythical Rake Cycle in 1909 in which there was no other evidence other than the few lines of verse of My Jewel My Joy.I agree there are many inaccurate liner composite lyrics that implore the use of likable nonsense and there's nothing wrong with that! Years ago I read there were over 2000 reported composites of the Irish folk played by american's. Write now interested finding songs directly related to a Dr. Patrick Donnelly aka Phelim Brady from 1697 and his passing in 1717 onward toward 1790 My Jewel, My Joy, don't trouble me with the drum aka "The Streets of Laredo"
