First the disclaimer as old as time: not preggo, not even trying.
Marnix is pronounced the way you think it’s pronounced. So I believe the nameberry database doesn’t know the name Marnix and maybe you’ll think it’s a made up name so I’ll tell you something about its history. It’s a ‘Dutch’ name with [name_m]French[/name_m] origins. It was introduced in the Netherlands by [name_m]Philips[/name_m] of Marnix, [name_m]Lord[/name_m] of [name_m]Saint[/name_m]-Aldegonde, [name_m]Lord[/name_m] of [name_u]West[/name_u]-Souborg. The ‘of Marnix’ obviously means that he was some kind of nobility. Marnix was apparently historically speaking a [name_m]French[/name_m] region, to be precise a [name_m]French[/name_m] village in the municipality of Nattages. He was a Flemish/Dutch writer/academic. People mistakenly assumed his name was Marnix of [name_m]Saint[/name_m]-Aldegonde and he was quite a respectable and honourable man and several streets and squares, also in [name_m]Amsterdam[/name_m], have been named after ‘Marnix’. So yeah that’s how a [name_m]French[/name_m] place name mistakenly turned into a given name in The Netherlands…
So since I’ve been hypothetically naming my hypothetical children I think Marnix would be a nice name that could survive easily in international contexts yet it’s still unique elsewhere and comfortably established in The Netherlands, so all in all it’s THE type of name I’m looking for. So would you agree?
