It's sung by Morag MacKay on Kenneth McKellar's "Highland Journey" and titled The Fairy Lullaby.
I left my darling lying here, lying here, lying here. I left my darling lying here to go and gather blaeberries. Hovan, hovan, etc.----- I've lost my darling baby, oh. ( I don't know gaelic either, so can't help you there.) i've heard more verses somewhere else but can't remember where at the moment. The lullaby was sung on this record as part of a medley so all the words weren't sung.
I hope this will help a little.
