There's another 17th century tune, this time called "The Fit's come over me now", also in 9/8 time, in MS Panmure 7 = NLS MS 9454, a violin score of about 1675, but I don't have a copy.

I suspect the "The Maulster's Daughter of Marlborough" was modeled on "The fits come on now". It went through a chapbook version called "The Longing Maid" before it became the "Whistle, Daughter, Whistle" in DT.
