Kate and William shocked the world when they announced that they'd named their third child Louis, or Prince Louis Arthur Charles, to be more precise. But we've been predicting a comeback for this classic name for a long time. 
Derived from the Germanic Ludwig, Louis is hugely popular in France, Belgium, and Quebec where it ranks in the Top 10, though it is also on trend in the UK, The Netherlands, Switzerland, New Zealand, Australia, and Germany, where it features in the Top 100.
