[3][4] The Forkhill Peadar Ó Doirnín GAA club was named to commemorate the poet.
[7] One of his poems, Mná na hÉireann, was later set to music composed by Seán Ó Riada and has been recorded by a number of 20th century artists including Kate Bush and Sinéad O'Connor.
[8] Other songs, such as Úrchnoc Chéin mhic Cáinte, make classic Gaelic appeals for a return to the solitude of nature.
