The name Adel or Adele came from a small town
in ancient Germany or Germania at the time.
This town was known for a tree that is hated and unreconised to this day,
"The Fartroses Tree"The Fartroses Tree was a tree that literally smelled like fart and scat.
The name originated because of the cure to stoping the smell.
People had to go and cut down these massive trees to stop the smell. They could die from being next to the smell for to long.
