Here is a triple composite of prince William, princess kate and their son prince George.
I added the name asteroids for fun.
The kate/George midpoint is opposed to William.
The Jupiter/juno(king/queen) midpoint is opposed to the sun/moon conjunction and the mercury/venus midpoint is conjunct the sun/moon conjunction.
From this I think William will serve as king and they will be the most popular royal couple in many years.
The only thing that concerns me is that Pluto is opposed to venus and the sun/moon conjunction.
This implies death with qualify this chart.
