minstrel: Child ballad # 14, question of date

[jpark6 at gmu.edu]

Greetings all!
   I'm writing because I'm trying to find out the date of Child Ballad # 14, called either Baby Lon, Babylon, Bonnie Banks of the Virgie-O, or Three Sisters.  I looked in Compleat Anachronist # 11 (Traditional Ballads), and it lists it as 1598 from a manuscript (without saying which one).  Everywhere else I look says that it's from between about 1850-1910.  Because these two dates are extremely different, I'm really leaning towards the later dates.  I'm really hoping that I can get a definitive answer one way or the other.
