I'm very curious about this, how does it affect the family tree and how would it be shown? this is one of my ideas: Have a bolded or highlighted line connecting mid way to the new form to show that they have been reborn. so dravus became Dravus® unbirthed by me. and I became Lorane® unbirthed by Zato( the ® sanding for reborn ). but new children with there respective mates would still be done normally and with there original form, hence why there is a square to the top left of the unbirthees box, showing that they have been unbirthed.

the family trees are only examples and are not the full family.
