This is what behindthename says about [name_f]Giselle[/name_f]:
I prefer [name_f]Giselle[/name_f], accent isn’t an option at all. I worry people might think [name_f]Gisele[/name_f] is more correct way to spell, but I see both as correct. I don’t think meaning is particular bad, I think of it as “pledge of my affection”, rather than hostage full stop. I also think [name_f]Giselle[/name_f] with two LL looks more complete and I don’t appreciate model association with [name_f]Gisele[/name_f]
