Alan-a-Dale (first recorded as Allen a Dale; variously spelled Allen-a-Dale, Allan-a-Dale, Allin-a-Dale, Allan A'Dayle etc.)
[1] Howard Pyle uses this tale in his book The Merry Adventures of Robin Hood, but changes several details.
He gives Alan's sweetheart the name Ellen, and introduces Friar Tuck into the story; Tuck is sought out specifically as the only priest who will perform the wedding in defiance of the bishop, and therefore, this tale is combined with that of Robin Hood and the Curtal Friar.
[2] In Pierce Egan the Younger's story Robin Hood and Little John, Alan is given the name Sir Allan Clare; he is an armed knight, not a minstrel, and he is the brother of the Maid Marian.
His sweetheart is Lady Christabel, the daughter of the Sheriff of Nottingham, who wants to give her to an old knight friend of his.
