Hello Randy

To clarify

William Forde, of Cork, was a 19th century musician and antiquarian, who collected songs and tunes, though his main interest was in tunes (5).

He was sent a piece which came to be called My Jewel, My Joy by one Mr Aldwell, who claimed to have heard it sung in Cork in 1790. It seems Mr Aldwell sent a written version of it, one verse and some music, also set down. But I am not sure there is even clarity about that.   

Forde's papers were later acquired by another song collector, P W Joyce. In 1909, Joyce published a selection from Forde's collection, and, eventually, donated Forde's materials to The Irish Academy (6).
As My Jewel My Joy was one of the Forde songs selected by Joyce, we can find the title, the words of the single verse provided by the informant, and the tune, in the selection published by Joyce in Boston in 1909 and now also available on the Internet. Joyce's publication is sometimes cited as if Joyce collected the song , but he didn't.

Richard Jenkins comes into it as much later he asked a friend/colleague to look through the Forde material in the Irish archive. Sadly they could not find anything relating to this song.
