My guess would be "yes". I've had a poke around the internet and not found much - just that the song might also be known as, "Thoir
mo shoraidh thar Ghunnaigh" and "Mo Nighean Donn Bhòidheach" (the latter v. confusing because at least one other (different) song exists with the same name. The singers liked their songs about brown-haired girls.

The translation I've seen of it makes it sound very traditional/unliterary.

Just a guess though.
