Big Tim: I across this poem by her entitled "Were I But His Own Wife" and here is the first verse.
"WERE I but his own wife, to guard and to guide him,
'T is little of sorrow should fall on my dear;
I 'd chant my low love-verses, stealing beside him,
So faint and so tender his heart would but hear;
I 'd pull the wild blossoms from valley and highland,
And there at his feet I would lay them all down;
I 'd sing him the songs of our poor stricken island,
Till her heart was on fire with a love like my own."

The reason I posted it is, that it seems to me reading through it, that there is much the same swing to it as in Carraig Donn. I must do a bit more research to try and ascertain who in fact did write Carraig Donn.
