Agata does not "chart" there.
It's funny anyway: I have hitparades for newborns in nearly 20 countries and big cities in my own database, sometimes sporting 500 or even 1000 names, going over several years, and
Agata does not chart a single time, anywhere.
Only
Agathe hoovers around place 50 for several years now in
France...
