A UK ballad. Try Martin Carthy's version first on one of his earlier albums or on a compilation called "Selections" where I heard it, as it might be easiest to find. A version by Ben Butcher, collected and recorded by Bob Copper is on "The Folksongs Of Britain Vol.IV: The Chid Ballads Vol.I" (Caedmon 1145) under the name of "Cruel Lincoln". It's also known as "Young Lincoln". Steeleye Span even did a reworking on "Commoner's Crown"

See if it's in the Digital Tradition. If not I'll try and find a text for you.
