"Women of Ireland", which I've even seen listed in publications as Trad. Irish but was in fact written by Sean O'Riada, who died in the late 60s.

"Shoals of Herring" and "I'm A Freeborn Man" by Ewan MacColl

"She Moved Through The Fair" (at least the words), though the author's name has drifted out of my mind unfortunately. Padraic Colum???

"Fields of Athenry" was written by a Dubliner known as Pete St. John though I understand that is not his real name.

"The Ladies Go Dancing At Whitsun" was written by Shirley Collins' first husband, John(?) Austin, to the tune of the Coppers' version of The Week Before Easter (or "A Week Before Easter" as they called it). They all lived not too far from each other in Sussex, which is probably where John first heard the air.

Non-British Catters may not realise that the dancing in question was not social dancing, and the ladies weren't simply doing it for amusement. They were preserving a spring tradition, customarily carried out by the men, which they didn't want to see die out. Unfortunately, the men were busy dying themselves, in the Great War. So none of them was left to dance. Instead it's their names which now stand beside the May pole in a fine roll of honour.
