I wouldn't see a problem in using Mazarine and Ségolène, def usable imo, even for a right wing person haha. And we now know for a fact that Ségolène
Royal is not going to govern
France these 5 next years. :) Mazarine makes me think of Mitterrand's daughter indeed (and Cardinal Mazarin) because it is unusal, but I can go past it. And there are worse associations. I don't think people abroad would make a connection.
I feel the same way about all the Lilou/Lili/Lala etc... it's just terrible. Names like Maëlys belong to this trend, I think it's better already but not my cup of tea anymore.
