Is the phrase "Lowland maids" traditional? There are quite a few songs that mention "sailing to the Lowlands" but does "Lowlands" refer to any particular country?

There's a version of "Lowlands Away" in F. Tozer's book, "Sailors' Songs or 'Chanties', 1910" that includes the phrase "Lowland maids" and then "Lowland men". I have not seen this phrasing in other versions of "Lowlands Away."

I'm refering to the shanty that starts off with:

I dreamt a dream the other night
Lowlands, lowlands away, my John
I dreamt I saw my own true love
My Lowlands away
