How do we feel about Fontaine or [name_m]Voltaire[/name_m] as a middle name for a boy?
For example name ideas:
[name_m]Noah[/name_m] [name_m]Voltaire[/name_m]
[name_m]William[/name_m] Fontaine
[name_m]Feel[/name_m] free to drop some other combos if you like these names 
Hmm, they’re both a bit harsh sounding to me. I get the inspiration behind [name_m]Voltaire[/name_m], but maybe it’s better as a GP name. I just think of Fontaine as the [name_m]French[/name_m] word for fountain. It could work easier as a middle name though.
I like Voltaire’s “eccentric aristocrat” vibe but Fontaine is a little strange to me. It’s just not a word I would use as a name. 
Bold and interesting - I think they work with the grounded first names.
I’d consider [name_m]Isaac[/name_m] [name_m]Voltaire[/name_m], [name_m]Jonah[/name_m] [name_m]Voltaire[/name_m], [name_m]Ellis[/name_m] [name_m]Voltaire[/name_m], [name_m]Ezra[/name_m] Fontaine and [name_m]Alec[/name_m] Fontaine
