Gendering of names

Question

I find the questions which ask things like "If I say "Tu es français.", who am I speaking to: Lucie or Hugo?" quite frustrating, because the gendering of
 names isn't fixed.  According to 
https://madame.lefigaro.fr/prenoms/prenom/garcon/lucie, Lucie, whilst 
predominantely feminine, has been a mixed name for over a century.  It might be helpful to add a hint to these kinds of questions that says "Hugo is male, Lucie is female".

Answer

I think you can safely go with the overwhelmingly vast majority and take Hugo as male and Lucie as female. A male Lucie would normally be called a Luc. ;)

Answer

Hi Sebastian, 
That is an interesting comment because I have the same problem with non-European names and need to check whether they are male or female.
I am gathering that the only problem was uniquely about Lucie as there are many different names in the exercise?
