See Vol. II- Ballads, Frank C. Brown Collection of North Carolina Folklore for "The Wee Wee Man", "Roy's Wife of Aldovaloch" and "I wish my love were in a ditch [mire]"."The frog came to the myl dure" is mentioned in "The Complaynt of Scotland", 1549, and folklorists think it was probably a version of "Froggie went a courting", but there is no known Scottish broadside of it of the 16th or 17th centuries.
"The Riddle Song" is given in facsimile from an English manuscript of c 1440 (BL Sloane MS 2593) in the Opie's 'Oxford Dictionary of Nursery Rhymes'
