Oh my gosh, congratulations! That is so exciting.
I was waiting for an update from you, and this is definitely a big one!
So, I’ll give my opinions on each name, and then list some I think would be good twin names.
Boys:
[name]Aaron[/name] - I’m not a fan of [name]Aaron[/name]. The double A’s throw me off for some reason… Lol. I also don’t really care for the sound of it.
[name]Alec[/name] - It feels dated to me, especially next to the names of your other children. [name]Alexander[/name] nn [name]Alex[/name] or even [name]Lex[/name] would an awesome alternative! I just wouldn’t go with [name]Alec[/name].
[name]Benjamin[/name] - Although I am normally opposed to using Biblical names myself, I love the name [name]Benjamin[/name]. It’s classic, it ages well, and it’s all around awesome. Plus, [name]Ben[/name] is an awesome nickname. [name]Mia[/name], [name]Zach[/name], Lo, [name]Ben[/name], and sibling sound awesome together. (I’ll fill in the sibling blank later lol.)
[name]Brian[/name] - Like [name]Alec[/name], this feels dated with the names of your other children. One of my closest friends is named [name]Bryan[/name], but he’s 19, and I just feel like [name]Brian[/name]'s time has come and gone. I also think of the dog from Family [name]Guy[/name] who, while hilarious, probably isn’t the best connection to have. Lol
[name]Declan[/name] - I love the sound of [name]Declan[/name]. I think it sounds modern and cool, but I agree with your concern that it doesn’t really work with the names of your other kids.
[name]Gabriel[/name] - Eh… I’m not a fan. I knew a kid named [name]Gabe[/name], and he was teased all the time because of his name, and I just wouldn’t want that happening to your kid (look at me, acting like I’ve known you forever or something). You definitely have better choices!
[name]Graham[/name] - I love the name [name]Graham[/name]. Like the names of your other kids, it feels classic to me and I can see it on a boy of any age. I know the funniest kid named [name]Graham[/name], and that’s what I think of when I hear this name. [name]Love[/name] it!
[name]Jeremy[/name] nn [name]Remy[/name] - I adore the name [name]Jeremy[/name]. I’ve always thought it was handsome and classic, and one I can see fittig every age. Personally, I’ve always loved the name [name]Remy[/name] for a girl, but I think it still sounds nice for a boy. My favorite nickname for [name]Jeremy[/name], though it may be a stretch, is [name]Jett[/name]. Either [name]Remy[/name] or [name]Jett[/name] as a nickname, [name]Jeremy[/name] is an all around wonderful choice.
[name]Lukas[/name] - I’m not crazy about it spelled this way. [name]Lucas[/name], on the other hand, is one of my absolute favorite names. I simply adore it, and I know two awesome [name]Lucas[/name]'s, and the nickname [name]Luke[/name] is awesome. [name]Love[/name] this name! Plus, [name]Mia[/name], [name]Zach[/name], Lo, and [name]Luke[/name] sound great together.
[name]Reeve[/name] - I think this name is wonderful. I would even suggest using it as a first name, I think it’s that great. I love the sound of it, plus it makes me think of [name]Keanu[/name] [name]Reeves[/name] (whose movie The Matrix was one of the best movies of all time), and let’s face it, he’s pretty hot. Lol. Plus I love that it honors your brother! So, whether you use it as a first or a middle, you should use it some way.
Girls:
[name]Ada[/name] - I think [name]Ada[/name] is really pretty, it’s simple and really sweet. But, for some reason, I’m not crazy about it without your other kids. Is that totally crazy? Maybe if I come back tomorrow my opinion will change (I’m super tired after nearly 4 hours of homework…)
[name]Adelaide[/name] - I love [name]Adelaide[/name]. I think it’s so pretty and timeless and just all around wonderful. You also have a variety of nicknames: [name]Ada[/name] (it could work, even if it starts with a long A), [name]Addie[/name] (while cute, I think it would be too trendy with your other kids), or [name]Heidi[/name] ([name]Lyndsay[/name] mentioned this a nickname for [name]Adelaide[/name], and I immediately fell in love. It would be awesome with your kids’ names). [name]Heidi[/name] is my favorite 
[name]Arabella[/name] - Pretty, but too trendy with your other kids names. Although the nn [name]Belle[/name] would be absolutely adorable with them… Hmmm… Maybe [name]Annabel[/name] nn [name]Annie[/name] or [name]Belle[/name]?
[name]Delia[/name] [name]Rosemary[/name] - Gorgeous. I think the name [name]Delia[/name] is stunning and I love that it’s so underused. [name]Delia[/name] [name]Rosemary[/name] is a beautiful combo, and will you be using two middle names for your twins, as well? Because [name]Delia[/name] [name]Rosemary[/name] [name]Charlotte[/name] would be so pretty.
[name]Julia[/name] [name]Charlotte[/name] - I have to say, I’m loving the alliteration of [name]Julia[/name] Johansson. It’s especially cute since you’re J. Johansson and your daughter would be J. Johansson. I think it’s sweet
This is definitely one of my favorites.
Liviana - Not crazy about Liviana… It sounds too extravagant and almost made up with the names of your other kids. [name]Livia[/name] nn [name]Liv[/name] would be super cute. Or even just [name]Liv[/name] if you wanted (which I love! It’s been on my list forever).
[name]Ramona[/name] - I think [name]Ramona[/name] is really pretty and classic, and a good way to get to the nickname [name]Romy[/name] that you guys like. Very cute, but I like some of your other choices better.
[name]Rosemary[/name] - I think this is absolutely gorgeous. It’s timeless and the nickname [name]Romy[/name] makes it cute and fun for a little girl and young woman. It’s pretty much a great choice.
[name]Sophia[/name] - I adore the name [name]Sophia[/name], but like you said, it’s too popular. Which is a shame, because it would be awesome with your other kids, but she’s be [name]Sophia[/name] J. in her class.
[name]Victoria[/name] - I don’t care for this name. I’m not sure why, but I think it’s the “ct” sounds harsh to my ears. After reading “Angels and Demons” I started to really like [name]Vittoria[/name], but I feel that’s too exotic with your other kids.
Some suggestions:
[name]Jack[/name]/[name]Jackson[/name] nn [name]Jack[/name]
[name]Dashiell[/name] nn [name]Dash[/name] (maybe not as classic as your others, but it still works)
[name]Annabel/name nn [name]Belle[/name]
[name]Willa[/name]
[name]Owen[/name]
[name]Andrew[/name] nn [name]Drew[/name]
[name]Livia[/name] nn [name]Liv[/name]
[name]Caroline[/name] nn [name]Cara[/name], [name]Carly[/name], or no nn
Twin set ideas (some include my suggestions…):
[name]Adelaide[/name] and [name]Benjamin[/name] nn “[name]Heidi[/name]” and “[name]Ben[/name]” (My favorite, I think. I don’t know if you like the nn [name]Heidi[/name], but I think it’s really cute)
[name]Annabel/name and [name]Jack/name nn “[name]Annie[/name] or [name]Belle[/name]” and “[name]Jack[/name]” (second favorite, even though they’re both my suggestions… Lol)
[name]Julia[/name] and [name]Benjamin[/name] “[name]Ben[/name]” (two great, classic names. [name]Benjamin[/name] and [name]Caroline[/name] would also be cute)
[name]Livia[/name] and [name]Lucas[/name] “[name]Liv[/name]” and “[name]Luke[/name]” (I know you don’t like matching twin sets, and neither do I, but I’ve always thought [name]Liv[/name] and [name]Lucas[/name] would be cute)
[name]Delia[/name] and [name]Owen[/name]
[name]Rosemary[/name] and [name]Andrew[/name] “[name]Romy[/name]” and “[name]Drew[/name]”
If it’s two boys:
[name]Jeremy[/name] “[name]Remy[/name]” and [name]Owen[/name] (classic yet modern, I like it)
[name]Benjamin[/name] “[name]Ben[/name]” and [name]Graham[/name]
[name]Benjamin[/name] “[name]Ben[/name]” and [name]Jack[/name]
[name]Jeremy[/name] “[name]Jett[/name]” and [name]Lucas[/name] “[name]Luke[/name]”?
That’s all I can think of for now… I’m so tired. But I hope this helps! Please keep us updated!
