A Dhochtúir Jennings, céad fároir cráidhte! Is tú fuair bás uainn i dtús do shaoghail: Dá siubhalainn Connacht agus Oileán Phádraic Samhail mo mhaighistir ní bhfuighinn i dtír Nuair a bhreathnuighim síos ar Pholl an Iarrain, Cé an cás dom bliadhain acht arís go deó, Ins an áit a h'oileadh an leannaibh uasal. Acht nach truaigh sin a's mo chreach, é'r lár!
