‘what you yourself and the late John O’Daly, following in the footsteps of Edward Walsh, to some extent accomplished for Munster, more than thirty years ago’ (iv)
John O’Daly (1800-1878) was an editor and publisher. He published Edward Walsh’s Reliques of Irish Jacobite Poetry (1844), as well as two series of Poets and Poetry of Munster, the first by James Clarence Mangan (1849), and the second by George Sigerson (1860). In another of his works, Mise agus an Conradh (1937), Hyde wrote ‘Ní raibh éinne, lena linn, a rinne níos mó ar a shlí féin chun Gaeilge a leathnú agus a shaothrú’ (There was noone, during O’Daly’s time, who did as much as he did to popularize Gaelic’, my trans.) The most comprehensive biography of John O’Daly is that in Beathaninéis, vol. 2, by Diarmuid Breathnach and Mairéad Ní Mhurchú. It is available online at https://www.ainm.ie/Bio.aspx?ID=1193
The most comprehensive biography I have found in English is the entry in The Oxford Companion to Irish Literature, edited by Robert Welch.
