Hmm. It kind of depends on what exactly the first name is, and also, more importantly, how much you care. If you don’t really care then I don’t see this affecting the daughters, but if it is the sort of thing that keeps coming up, then maybe it could a bit.
I don’t think you have to balance [name]Seraphina[/name] with a more neutral middle name if you use it. [name]Seraphina[/name] [name]Katherine[/name] is a fine combo. Especially if you are able to get a [name]Concord[/name] MA allusion in there, that will tie them in nicely without feeling like you have to keep going on with the gender thing. I think [name]Seraphina[/name] could be a nice middle if you find another first you like too, btw.
I frankly find [name]Seraphina[/name] very trendy. I do think it’s beautiful and I don’t think it will be the next [name]Isabella[/name] (but I also don’t think of [name]Isabella[/name] as exactly trendy - more just an old name that’s newly popular). But I just do think of the Afflecks every time I hear it. I don’t think that’ll last forever and I know plenty of people won’t react the same way. But just be aware of it, because I’m also not alone. If you love the name enough that shouldn’t matter, but if you want to keep looking, then do for now.
I have no idea who’s from [name]Concord[/name] MA! Let me google in a sec, but first, a few other options:
No to [name]Serena[/name]? What about:
[name]Selena[/name]
[name]Helena[/name]
[name]Irena[/name]
[name]Marina[/name]
[name]Carina[/name]
Like [name]Seraphina[/name] in ways, but less frilly/trendy/celebubaby:
[name]Fiona[/name]
[name]Phoebe[/name]
[name]Sophia[/name]
[name]Angelina[/name] (also celebrity in a way, but less so)
[name]Philippa[/name] (also feels boyish in its way for the overlap with [name]Philip[/name]. Also pretty trendy though with [name]Pippa[/name] Middleton)
And then we have:
[name]Josephina[/name]/[name]Josefina[/name]/[name]Josephine[/name]
If you like that, I think it might be great - she gets [name]Jo[/name] as a nickname to be boyish/neutral like her sib, and you have a character tie in at least to [name]Louisa[/name] [name]May[/name].
I also think [name]Alcott[/name] would be a pretty cool, and gender neutral, name for a girl. Nn [name]Ali[/name]?
[name]Alcott[/name] [name]Seraphina[/name] even is very nice. [name]Seraphina[/name] [name]Alcott[/name] is also fine.
OK, googling [name]Concord[/name] MA authors…
Well I think I found your daughter’s name for the most famous example - won’t type it in case you are trying to keep it out of here - In case that is her name, for what it’s worth, this was also a celebrity baby’s name many years ago (but I think most everyone’s forgotten, proving it wears down overall). I actually kind of like this with [name]Seraphina[/name] - something with the r, and the beginning of the name sounding like another girl’s name.
[name]Thoreau[/name] - I think this makes a very fresh girls name, although it might be over the top depending on what your daughter’s name is.
[name]Hawthorne[/name] - this could be cool! Might be more of a middle name though. I find it very masculine feeling.
[name]Margaret[/name] - first pen name of either [name]Harriett[/name] Lothrop. Doesn’t sound like the best fit with your current daughter’s name, or maybe even your taste?
[name]Harriett[/name] - see above.
[name]Sidney[/name] - last pen name of one of Lothrop. Could it work? Certainly uni, and I don’t think it’d be horrible to spell it [name]Sydney[/name].
[name]Sophia[/name] - was [name]Nathaniel[/name] [name]Hawthorne[/name]'s wife, and kind of feels similar to [name]Seraphina[/name].
[name]Nathanielle[/name] - a stretch, but quite pretty really and romantic in a similar way to [name]Seraphina[/name].
[name]Polly[/name] - was a character in one of Lothrop’s stories.
[name]Sophronia[/name] - I am assuming this is a form of the character Phronsie’s name (one of Lothrop’s characters). Feels sort of similar to [name]Seraphina[/name]. However it is pretty out there and clunky.
[name]Abigail[/name] - [name]Louisa[/name] [name]May[/name]'s mother…
[name]Pauline[/name] - a character in one of [name]Louisa[/name] [name]May[/name]'s early works.
Good luck!
