Paul, here are the lyrics taken from "50 beauties of Erin"

Killarney

1. By Killarney's lakes and fells,
Emeralds Isle and winding bays,
mountain paths and woodland dells,
mem'ry ever fondly strays,
bounteous nature loves all lands,
beauty wanders everywhere
footprints leave on many strands
but her home is surely there.
Angels fold their wings and rest
in that Eden of the West;
beauty's home, Killarney,
heav'ns reflex, Killarney.

2. No place else can charm the eye,
with such bright and varied tints,
ev'ry rock that you pass by,
verdure broiders or besprints.
Virgin there the green grass grows,
ev'ry morn Spring's natal day,
bright hued berries daff the snows,
smiling winters' frown away!
Angels often pausing there
doubt if Eden were more fair,
beauty's home, Killarney,
heav'ns reflex, Killarney.

In case you'd like to have a photocopy of the (piano) setting, mail me: hell@psy.uni-muenster.de

No further information on author is given in my source, a piano book. I even cannot say if there are more than two verses, for in this book the number of verses printed is limited to what fits on the rest of the page.
