boy or girl names. we’re considering it for our first child, but worried that we won’t know what to name his siblings becuase we can’t think of ANYTHING that goes with it, which is a shame because i really like it. HELP!
This one is almost too easy for the nameberry mavens! But for starters, I’d direct you to this Name Game featuring dozens of [name]Balthasar[/name]-friendly ideas: https://nameberry.com/nametalk/viewtopic.php?f=9&t=33&hilit=[name]BALTHASAR[/name]

Oh wow, thanks for all these names! Off your list I really like [name]Phineas[/name], [name]Atticus[/name], and [name]Cassius[/name]. I really like [name]Rupert[/name] too, but am reminded of the cartoon bear, maybe [name]Rufus[/name] instead? I also like [name]Frederick[/name] but think it might be too common, and [name]Dashiell[/name], [name]Lawrence[/name], and [name]Oliver[/name] but am not sure if they would fit. I’m not that crazy about biblical names in general (when I think of [name]Balthasar[/name] I think of the Gettys, classy and powerful, not the magi. However the connotation doesn’t bother me, I just don’t want that theme at all)
For girls I really like [name]Clementine[/name] and [name]Evangeline[/name] a lot. I’ve also been thinking about [name]Mathilda[/name], [name]Imogen[/name], and [name]Briony[/name] (the matching inital has pretty much thrown this one out though, but I think it’s a great name). I also like [name]Hadley[/name] a lot. In general I’m not a huge fan of really frilly or feminine names, [name]Clementine[/name] and [name]Evangeline[/name] are as frilly as I’ll go ( and I don’t think they are at all, their quirkiness saves them)
For names in general I really like British naming. They seem to know how to pull of names that are quirky yet classic and charming all at the same time.
Oh and I also like [name]Orlando[/name], [name]Auden[/name], [name]Abbott[/name], and [name]Josephine[/name].
