Does anyone know about the story or additional verses for this Labhrás Ó Cadhla sean nos song? English song title might be "The Dawn."

I have found a recording of only one verse on a CD from a Swedish traditional ensemble from Finland, and I'd like to learn more verses. Unfortunately, it is not on the RTE recording of Labhrás Ó Cadhla. Here's the only version that I have. Please pardon the missing fadas.

Do shuios-sa sios go sciosmhar atuirseach
Gan aon fhonn casadh orm go fainne an lae,
Fi shail an toir draighni bhi fillet calcaithe,
Is gan de chludah leapan im ghar ach e-
Go bhfacaios-sa lem thaoibh an ri-bhean mhaisuil
A chealg mo chroi le saigheadai daingeanna;
Ba dh'i an ainnir thar t'r i ar cloiodh an dragan lei
Is d'fhuig na milte marbh le gra da sceimh.

If the above verse sounds at all familiar, I would appreciate any help you could give me to point me in the right direction. The recording of the song is hauntingly beautiful. I'm just starting a Conradh na Gaeilge course this year.

I suppose that noone knows. Ta bron orm.

Beir bua agus beannacht

I've heard a wonderful version of Fainne an Lae by Muireann Nic Amhlaoibh a native of Corca Dhuibhne, who also sings with the trad group Danu.

She has an album of the same name:

Thanks, that's a good guess. I have Muireann's albums, but she recorded a different song. I will see Muireann the last week in June. If I sing the verse for her, maybe she might recognizes the verse.

Otherwise...
Does anyone know if there are any sean nos resources in Wexford? A library with an archive or a person I could visit and record? (Just amatuer digital stuff.) Please recommend details. I leave for Shannon on June 20.
