This verse doesn't occur in the earlier English versions but the following similar stanza is in versions of 'Little Rosewood casket' a similar song.

I must say farewell, dear sister,
Place my hands upon my breast.
I am dying. Kiss me sister.
I am going home to rest.

Whilst this doesn't really help your query the Carter stanza may have been pieced together using this stanza.

Here's a possibility
Lay your brow upon my breast.
