Oh, what a lovely old lady!

Yes I think many of the old folk tales are mirroring archetypical themes of life. One thematic storyline is something like this: for some reason parents abandon a baby in the woods, but a way or another the baby survives and grows up to be kind of a superhuman with exceptional powers. Bremen Musicants mixes in a version of that theme - the outcasts band together and become stronger and happier than they ever were before =)
