Did you notice that alot of the Child ballards have stories about dragons and they're basically the same story, but with different characters and the gender of the dragon changes from story to story.

Not sure which stories you are talking about care to sum them up or give me a link so that i can read them

The Child Ballads are a collection of 305 ballads from England and Scotland, and their American variants, collected by Francis James Child in the late nineteenth century. The collection was published as The English and Scottish Popular Ballads between 1882 and 1898 by Houghton Mifflin in 10 volumes.

Do a little research and come back with you're relpy.

I must warn you that these ballads are kind of nutso and I'm not just talking about the one who are about dragons.

P.S. I asked because I think a loathesome dragon(the story I talked about on my intro) is inspired by a number of these ballads (And I am not just talking about the ones related about dragons), but I want an expert's opinion.

My only guess is it is the same reason a lot of things now days have almost the same story or sound to it. Someone may know about one version of the ballad, then add their own twist to it. Given the age of some of them it seems reasonable. Somewhat like a remix of a song now days.
