Richie - the Harris ms is at Harvard: Guide to papers relating to the Harris ms. Their librarian may be able to confirm what, if anything, was written at the head of this.

That page also has: For a detailed description of this manuscript see: Harris, Amelia. The song repertoire of Amelia and Jane Harris, edited by Emily Lyle, Kaye McAlpine, Anne Dhu McLucas. Edinburgh: The Scottish Text Society, 2002.. There may be information there.
