last stanza (in the edition reprinted by Percy) it could be

Awa, Awa, ye wild woman
Woe tae ye, ill death may ye dee
Gin I had kend he'd bin your son,
It's true ye've never been straight with me
O blame me not, O Lord Barnard
Enough of the blame, enough of the shame
With that saim brand pierce my heart
Ease me, ease me o' my pain.
