A tune family, compiled from various sources:
Gilderoy, Green Shores of America, Maria Martin, Lazarus, Come all you worthy Christians, The Peacock, Star of the County Down, Unquiet Grave, King Herod and the Cock, The Tree in the Wood, Bonaparte's Retreat, The Babe of Bethlehem.

I've heard of "The Star of the County Down" for years, but I've never seen a copy of text or tune, and I've never heard it sung. The only copies I can trace are one in H. Hughes' 4th vol. of Irish Country Songs, (which I don't have) and another in Edith Fowke's manuscripts. I can only presume that I have the right tune in mind.

Herrmann and Huntington give several songs to the tune.

"My love Nell" (a song by Wm. Carleton) is said to be another variant of the tune, and it is said that "The Tailor and the piper" was the original name of "The Star of the County Down".

"Lonely Banna Strand" is another song to the tune, with an ABC in a recent thread.
