That too.
They found one of those creepy dolls they left behind for the baby at the "Alephantis" Called a "Changling" Baby replaced with a voodoo -like doll
If you read the words to the song "Tam Lin" - there's various version. The long version is not in this song. It's about a girl who wanders on to Manor's property, becomes pregnant with the man there. He tells her how there is spell on him [mind control] He's under an older woman's spell and trapped there.
Supposedly the "fairy queen" has him enchanted and imprisoned.
The girl "Janet" rescues him on another cross - quarter day; Halloween, at, or soon after, a ritual. He changes into different forms [metaphor for mind control] "Changling".
Babies were snatched for work in circuses and carnivals. In those cases often the child was damaged on purpose; to create a freak and to make money.
The cross-quarter days are when children are snatched. [for the rituals on those days?]
The "away with the fairies" is when their soul is gone. But there is actually real abduction of babies.
Rhianna //Pop star was named after this song.
