These are my favorite middles. 
DH won’t let me use these as FNs, but I don’t mind putting them in the middle position as long as I get to use them at all. So what do you guys think about these? [name]Feel[/name] free to add to my list!

Awww, I really like [name]Astoria[/name] (+10 for being an obscure HP reference) 
[name]Calliope[/name], and [name]Atalanta[/name].
The only ones I dislike are [name]Boheme[/name] and [name]Euphemie[/name]. I think Bluelily is awesome, and I’d love to see it used as a middle name!
Bluelily - Interesting. I like it! I probably wouldn’t use it, but I like it!
[name]Boheme[/name] - I don’t like this one at all…
[name]Euphemie[/name] - Meh.
[name]Genevieve[/name] - This used to be one of my favorite names. I still like it.
[name]Henrietta[/name] - Never really liked it.
[name]Persephone[/name] - I know how this is pronounced now, but when I was younger, I thought it was “PURSE-eh-fone”, and that pops into my head every time I see it. Cute name, though.
Poeme - Cute!
[name]Serafina[/name] ([name]Seraphina[/name]) - Never really liked this, either.
[name]Sunday[/name] - I’m not a big fan of day-of-the-week names…
[name]Valentina[/name] - Adorable!
@balloonsforellie - Thanks
Bluelily ([name]Blue[/name]-lily?) -Not a fan this one
[name]Boheme[/name] -I don’t mind this one
[name]Euphemie[/name] -On the fence about this one
[name]Genevieve[/name] -[name]Love[/name] this a fn & mn
[name]Henrietta[/name] -[name]Love[/name]
[name]Persephone[/name] -I’ve never liked this name
Poeme - This is such a lovely & sweet name
[name]Serafina[/name] ([name]Seraphina[/name]) - I prefer [name]Seraphina[/name]
[name]Sunday[/name] -Reminds me of [name]Nicole[/name] Kidman’s daughter [name]Sunday[/name] [name]Rose[/name]
[name]Valentina[/name] -This is a lovely name
These are the names that I like from your list:
[name]Genevieve[/name]
[name]Henrietta[/name]
[name]Persephone[/name]
[name]Serafina[/name] ([name]Seraphina[/name])
[name]Valentina[/name]
Thanks for all the feedback so far everyone! It’s good to know that I’m not absolutely crazy (as my family would have me believe) for liking some of these.
Bluelily ([name]Blue[/name]-lily?)- I actually like this one. It sounds kind of pretty.
[name]Boheme[/name]- Not a fan, but I can see the attraction.
[name]Euphemie[/name]- Like.
[name]Genevieve[/name]- [name]LOVE[/name]! [name]LOVE[/name]! [name]LOVE[/name]! [name]One[/name] of my all time favorite names.
[name]Henrietta[/name]- [name]Love[/name] it!
[name]Persephone[/name]- Greek mythology, automatically makes me love it.
Poeme- Maybe without the extra e I would be partial to it.
[name]Serafina[/name] ([name]Seraphina[/name])- Prefer [name]Seraphina[/name], but also one of my all time faves!
[name]Sunday[/name]- It’s okay.
[name]Valentina[/name]- [name]Love[/name] it!
Bluelily is pretty and edgy! I also like [name]Persephone[/name] and [name]Sunday[/name].
Hmmm, that’s interesting. I didn’t think Bluelily would be very popular with you, berries! After I thought about it more, I got worried that it would come off as a try-hard version of [name]Beyonce[/name] and [name]Jay[/name]-Z’s daughter, [name]Blue[/name] [name]Ivy[/name].
Bluelily ([name]Blue[/name]-lily?) - Not a fan.
[name]Boheme[/name] - Not a fan.
[name]Euphemie[/name] - Not a fan.
[name]Genevieve[/name] - Not bad.
[name]Henrietta[/name] - Not bad.
[name]Persephone[/name] - Not a fan.
Poeme - Not a fan.
[name]Serafina[/name] ([name]Seraphina[/name]) - [name]LOVE[/name]!
[name]Sunday[/name] - Not a fan.
[name]Valentina[/name] - Not bad. Probably my second favorite.
I think we just like different kinds of names! I think just about any name can go in the mn spot, though, within reason. (Examples of when it’s NOT ok: [name]Adolf[/name] Hitler, Ayrian Nation, etc.)
[name]LOVE[/name] [name]Astoria[/name]! I wouldn’t be brave enough to use it, as probably my entire family would hate it, so it’ll stay a guilty pleasure name for me!!
My fave is [name]Valentina[/name], hands down! I also like [name]Seraphina[/name] & [name]Genevieve[/name]. Could I suggest [name]Penelope[/name], [name]Evangeline[/name] & [name]Matilda[/name]?

I do like [name]Valentina[/name] & [name]Henrietta[/name].
Yeah, you’re right! I like to go kind of crazy in the middle. You seem to like short and spunky instead of frilly and sweet. But that’s okay, because it would be boring if we all liked the same things. I do really like [name]Camille[/name] from your siggy, though.
Ooooo some good ones. 
I love [name]Leonora[/name], [name]Emelina[/name], [name]Noella[/name], [name]Rowena[/name] (though, I don’t think I’d ever use it,) [name]Tatiana[/name], [name]Thomasina[/name] ([name]LOVE[/name],) [name]Floriana[/name]. I also like [name]Evangeline[/name], cbeebiesmummy.
I love [name]Genevieve[/name] and [name]Serafina![/name]
I like all but Bluelily, [name]Boheme[/name], Poeme, and [name]Sunday[/name] (the least name-ish I guess.)
It so depends on what first name you choose. [name]Genevieve[/name], [name]Persephone[/name], and [name]Serafina[/name] are probably my favorites. [name]Lacy[/name] and elegant.
Yeah, you’re right emmabobema! Maybe I’ll make a board for combos, sometime. lol
