Here are two sources that are current today, in March 2021.

The Lester Levy site has four old versions of the sheet music. Search for Rose of Allandale. The antepenultimate line is "unblest by Fortune's gale." (Links to specific songs on this site never seem to work, so you have to do a search every time.)

The abcnotation site has two versions of the melody, one in 3/4, one in 4/4.

I didn't look at all four pieces of sheet music to see if the lyrics are the same throughout.

I enjoy playing this melody on my old piano.
