I found this set of words. They are attributed to a Robert Allan who lived from 1774 to 1841

"Will ye gang tae the Heilands, Leezie Lindsay?
   Will ye gang tae the Heilands wi' me?
Will ye gang tae the Heilands, Leezie Lindsay,
   My bride and my darling tae be?"

"To gang to the Heilands wi' you, Sir,
   I dinna ken how that may be,
For I ken nae the road I am gaeing,
   Nor yet wha I'm gaun wi'."

"O, Leezie, lass, ye maun ken little,
   Syne ye dinna ken me;
For I am Lord Ronald MacDonald,
   A Chieftain o' high degree."

"Oh, if ye're the Laird of MacDonald,
   A great ane I ken ye maun be;
But how can a chieftain sae mighty
   Think o' a puir lassie like me?"

She has gotten a gown o' green satin.
   She has kilted them up tae her knee,
And she's aff wi' Lord Ronald MacDonald,
   His bride and his darling tae be.

The various versions in Child tell a similar story but with added detail which takes off the romantic gloss somewhat.
