Cancer is famous for wanting to settle down into family life, and may even be the "mom" of any group before having kids.
Prince William, a fellow Cancer, seemed destined to be a father as much as bring the future King of England. After losing his own mom, Princess Diana, he continued his education at four schools before marrying longtime love Kate Middleton in 2011.
With the birth of two royal heirs in 2013 and 2015, the Prince has set himself up as part of the royal dynasty for years to come. He continues his mom's legacy of good works in Britain, Africa and around the world.
