Child A a, the broadside, is named: "Fair Margaret's Misfortune, or, Sweet William's Frightful Dreams on his Wedding Night. With the Sudden Death and Burial of those Noble Lovers." It was printed for Sarah Bates, at the Sun and Bible, in Giltspur Street.
John Ashton (A Century of Ballads) for example, has "take" stanza 1 and "grove" stanza 6.
Child has 1611 (is it 1613?) for "Burning Pestle":
As Percy has remarked, the ballad is twice quoted in Beaumont and Fletcher's 'Knight of the Burning Pestle,' 1611.
