Previous poster got it right on. [name]Stella[/name] is so flexible because it comes from Latin for star and that goes even back to older roots, shared with [name]Esther[/name] in Persian, which got into the Bible, and so has a Hebrew connection. So, she works well enough with Biblical [name]Abram[/name] and [name]Asher[/name] and [name]Seth[/name]. But, it’s really Latin, so it goes with [name]Leon[/name] ([name]Star[/name] and [name]Lion[/name], pretty darn cool!). And, most Latin names got picked up at some point in the Scandinavian countries, so [name]Lars[/name] works too (where [name]Asta[/name] or [name]Astrid[/name] are the truly local, implied representatives in the [name]Esther[/name]-[name]Estelle[/name]-[name]Estrella[/name]-[name]Stella[/name] family).
[name]Eliana[/name], without looking it up, feels like some Hebrew names I know ([name]Eleora[/name], mainly, and it also looks like [name]Eli[/name] + [name]Anna[/name]), so that’s fine with [name]Abram[/name], [name]Asher[/name], and [name]Seth[/name], and with that -a ending feels Latin enough for [name]Leon[/name] (although I think the sounds are too close for many people’s taste – [name]Leon[/name] is basically inside [name]Eliana[/name]). On the flipside, they will share a connection. [name]Eliana[/name] is enough like [name]Elin[/name] or [name]Elinor[/name] to go with [name]Lars[/name], although that’s the farthest stretch. So it’s pretty viable.
[name]Everly[/name], though, just feels very modern with these boys’ names that have history. Obviously do what you like, the names will have plenty of charms, and matching just won’t be one, so much. I can sort of see it with [name]Leon[/name], because it’s less traditional than the others. [name]Lionel[/name] or [name]Leander[/name] or even [name]Leonardo[/name] (because of DiCaprio, and [name]Everly[/name] sounds like a movie star or something) seems more possible.
I know you said you’re done with girls’ names, but I have always loved Evera and I think it’s more flexible, you could call her [name]Everly[/name]. And I’m done : D.
Others for [name]Everly[/name]:
Instead of [name]Asher[/name], [name]Ashton[/name]?
Instead of [name]Abram[/name], [name]Graham[/name]?
Instead of [name]Seth[/name], [name]Stone[/name]?
Instead of [name]Lars[/name], [name]Stellan[/name]? [name]Soren[/name]? [name]Ingo[/name]? [name]Corbin[/name]?
I like all the boys’ names. I think [name]Seth[/name] is by far the most familiar, [name]Asher[/name] is fast on the rise, [name]Abram[/name] and [name]Leon[/name] are somewhere below that, and people will be confused by [name]Lars[/name] (I mean, they’ll probably have heard it, but unless you have a very Scandinavian last name, they’ll be a little surprised).
Good luck!
