WHEN YOU DON’T MEAN TO HAVE A THEME … BUT YOU DEFINITELY HAVE A THEME

Allie writes:

When we named our son and daughter, we just picked names we liked. Our children are Kai William and Wren Kennedy.

My husband really wanted Kai for our son, and so he let me pick Wren for our daughter. William is for my dad. Kennedy was the name he wanted for Wren’s first name.

I am due with our third child in March. We don’t want to find out if it’s a boy or a girl this time, but it’s making names harder.

We realized, after we named Wren, that we had a theme. Very short names with nature-y meanings. I kind of love that, and the way there’s an image that goes with both names.

But it’s making naming even harder.

My husband’s favorite name for a girl is Avery, and I like it, but NOT with Kai and Wren.

We don’t want anything too different, but also not too old.

My favorite name for a boy is probably still Hudson, which I liked with both pregnancies, but I don’t like it as much with Kai and Wren.

Can you help us come up with some names that sound good with Kai and Wren? I feel like I have pregnancy brain all the time now, and every name I think of is just someone else’s kid already!

Please read on for my response and leave your thoughtful suggestions in the comments.

MAYBE YOU DON’T HAVE TO MATCH 100%

Abby replies:

Congratulations on your third!

Let’s start with this: yes, it makes sense to match your older kids’ names. Kai, Wren, and Hephzibah would be off-putting.

But maybe you don’t have to match in every category. I can describe Kai and Wren as:

  • Nature names
  • One-syllable names
  • 2020s favorites
  • Vaguely unisex (though Kai is far more common for boys and Wren is used in far greater numbers for girls, so … vaguely)

It just so happens you’ve matched on four out of four categories with your first two kids. But a name like River might work, too, right? It matches three out of four categories. Kai, Wren, and River. Or maybe Kai, Wren, and Liv. It’s not quite a nature name, but it sounds exactly right with Kai and Wren.

Also: after thinking through middle names, I realized that your kids share the same initials, reversed: K.W. and W.K. Which is … whoa, a lot of matching! But it seems subtle, particularly because Wren doesn’t sound like a W name. So I’m not thinking about initials at all … but it’s one more way you might feel like your kids’ names could be matched.

Okay, let’s jump in, because as soon as I started thinking “what if we just match in two or three of the categories,” the possibilities really opened up!

A SISTER FOR KAI AND WREN

BRIAR

A nature name used for boys and girls, Briar is fresh and modern, but with a hint of fairy tale, too. (Another name for Sleeping Beauty is Briar Rose.)

HAVEN

A word name that suggests safety and rest, with a strong, bright sound.

JUNE

A little more old-fashioned than Kai and Wren, June still sounds just right.

LIV

The first name that came to mind. It could be short for Olivia, but Liv is a distinct Scandi name originally meaning protection, but now strongly associated with life. I like the V sound, as in your husband’s favorite, Avery.

MAEVE

Another name with a V. Before I added Maeve, I thought about Mae – but it’s not as substantial as June or Maeve. It’s the name of a warrior queen from Irish legend.

REEVE

See a theme here? Eve is an obvious possibility, but surname name Reeve reminds me of Avery, Kennedy, and Hudson, but with a sound that matches Kai and Wren. As with several names I’ve mentioned here, Reeve could work for a daughter or a son.

RORY

An Irish name meaning red king, Rory is traditionally masculine, but has been used in small numbers for girls for ever. (And ever since Gilmore Girls, it’s clearly unisex.) The color association isn’t the same as a nature name, but it’s a similar vibe.

SAGE

Then again, Sage is The One Name that might check every box, matching on four out of four. Besides the herb, sage is also a lovely shade of a green and a synonym for wise. Kai, Wren, and Sage are perfectly matched – if that’s the direction you want to go.

A BROTHER FOR KAI AND WREN

FINN

Finn is a hero name from Irish legend, but there’s just a hint of the natural world, too. I love Kai and Finn as brother names, and I think it’s different enough from Wren, too.

HEATH

Thanks to a television Western from the 1960s, Heath had a good run in the twentieth century. But it wasn’t ever especially popular, so I think this nature name still has plenty of potential now.

JUDE

It’s brief and bright, a logical brother for Kai.

KNOX

Normally I might not suggest two single-syllable names starting with the same initial. But Kai and Knox sound nothing alike. Because you and your husband are also drawn to surnames, I wonder if Knox might be just different enough to satisfy?

LEO

It’s a nature name, but in a more vintage, old school way than Kai or Wren. But it’s plenty popular today and I think that makes it a match.

RIVER

Yes, it’s longer than Kai, but it’s a perfect brother name still. They both refer to water, they’re both modern favorites that you wouldn’t have heard thirty years ago, and while River is more common for boys, it’s also used for girls.

ROWAN

Like River, Rowan can be considered unisex. It’s an Irish surname meaning red, but it’s also the rowan tree – which has red berries.

TATE

A happy, upbeat name, Tate sounds and means cheerful.

Overall, I think my favorites for a girl are Liv and Sage. Something like Liv Allison or Sage Katherine, maybe, for your name? For a boy, I think Jude Hudson would be great. I’d love to suggest River Hudson, too – except that’s oddly close to New York’s Hudson River, so I’ll suggest River James instead.

  1. As Abby has pointed out in other posts, two names with similar qualities constitute a trend, but three similar names make it a theme.

    If you might have more children after this one, you’ll want to consider which elements you’re committed to keeping for every child. If you don’t want to be locked in for future children, this is your opportunity to break the trend.

    On that note, I think Avery and Hudson both go great with Kai and Wren. They are both modern, but not “out there”. I think you could use either one for your next child.

    However, there are plenty of lovely names that could fit most/all of your existing criteria…

    Abel
    Adair
    Alder
    Arbor
    Ari
    Aria
    Ash / Asher / Ashton
    Atlas
    Aven
    Avi
    Blake
    Brook / Brooke / Brooks
    Cedar
    Cora
    Coral
    Echo
    Ember
    Flora
    Forest / Forrest
    Isla
    Ivy
    Lake
    Lark
    Lief / Leaf
    Lily
    Luna
    Lyra
    Mica / Micah
    Noa
    Nova
    Pearl
    Petra
    Sol
    Vita

    I especially like Lark, which shares the K sound of Kai and the avian meaning of wren.

    Ultimately, though, I think any name you and your husband love will “fit” with your existing family names!

  2. Great suggestions already for girls and boys. I like Knox (on theme with the silent K) and also Heath and Finn for boys.

    Other ideas:
    Liv made me think of Neve!
    Willow
    Iris
    Suvi
    Lumi
    Rose
    Eve
    Eden
    Sylvie
    Calla

    Reese
    Winter
    Lux
    Hayes
    Saul
    Neil

    I’m drawn to both Neil and Neve as options for short, sweet, nature-y names!

  3. I actually think Avery works really well! It’s two syllables but brief, and vaguely gender neutral. It’s a popular, 2020’s name, too. Kai, Wren, and Avery. I think it fits!

    1. Funny, reading this comment to myself, I heard the word “Aviary” instead of Avery, and while it’s not the same, it kind of is!!

  4. Here are my ideas, without looking at the others. Iโ€™ve known real people with a lot of these names and they didnโ€™t run into any issues from the names.
    Boys: Ash, Baird, Bard, Birch, Blaze, Fen, Flint, Fjord, Glen/Glenn, Jasper, Onyx, Vale
    Girls: Aspen, Fjord, Lake, May, Mica, Onyx, Spring, Vale
