Future sibling names aren’t always top-of-mind when we’re naming a child. But they matter. After all, when we decided to call our daughter Clio, we forever closed the door on another favorite name – Theodore, nickname Theo.
Or did we?
For every family that decides Maya and Milo are too similar, another embraces the sound-alike names.
Or insists that Alicia and Alina are totally different names.
Some parents might never notice that Joanna and Jackson are both related to John.
Or maybe the first time Kelly introduces her daughter Grace, she suddenly realizes that the legendary Grace Kelly is echoed in their names.
Siblings’ names will be said together countless times. The names we like often have much in common.
So how can you tell if your sibling name choices make for a compatible set, or if they’re much too close?
There are no hard-and-fast rules, but here are ten factors to consider. They start mild, maybe-rethink-this kind of considerations. As we reach the top of the list? By #3, it’s best to think long and hard about your choice.

10. The names share the same meaning.
This can be a subtle way to link siblings’ names. Think Lucy and Claire. One means light; the other, clear. Felix and Asher both mean happy.
Sometimes the challenge comes when your family of two ends up a family of four or five or more. Your first two are the nicely paired Hazel and Ivy, but after using Olive and Jade, your choices for #5 narrow to Loden, Fern, and Moss.
It’s not necessarily a problem, but it might feel limiting as your family grows.
9. The names share the same origins.
Name enthusiasts know that Jacob and James are related. A popular combination for twin girls is Isabella and Elizabeth – two forms of the same name, even if it’s not quite like choosing Mary Anne and Marianne.
Origins aside, Jack and Sean make for a compatible pair of brothers’ names. And Charles and Caroline seem different enough to be worn without incident.
Daniel and Danielle, however, probably feel too close. Partially, it’s the shared origin. But the name also check a lot of boxes further up this list.
8. You’ve neglected 25 letters of the alphabet.
Sometimes this is unintentional. You’re naming your sons after their grandfathers – Michael and Matthew. Or you just happen to like the names Josie and Jude.
But let’s say you choose a letter with fewer options.
I remember hearing about a family with four sons – Henry, Heath, Hugo and Hatrick. Are they ice hockey fans, or was Harvey not their style?
And if you’re on the second generation sharing the same initial for sibling names, your options might be very limited.
7. The sibling names are (romantically) linked in history or pop culture.
If the movie was a bust, or we’re talking minor comic book characters, this matters not at all.
(You can safely ignore “But Sami named her twins John and Alice on Days of Our Lives.”)
Some combinations might appeal because of their shared connections. Imagine daughters named for two Jane Austen heroines, as in Emma and Elinor.
Then there’s Gillian Anderson’s threesome – Piper, Oscar, and Felix. Her kids might not know The Odd Couple, and it’s not a negative reference, either – so that’s probably a non-issue.
Some do feel truly unthinkable – siblings named Romeo and Juliet, maybe. The biggest challenge for overly matched sibling names? Probably famous romantic partners. Albert’s sister can’t be Victoria, and if your favorite name for a girl is Bonnie, strike Clyde from your boy’s list forever.
Though, of course, it can happen after the fact – in which case, all you can do is laugh and promise that, no, the Twilight novels didn’t inspire you to name your children Jacob and Bella twenty years ago.
6. Your choices can lead to same nickname.
Sure, you never intend to call Katherine or Kaitlyn by the nickname Katie. But it could easily happen. And how will their sister Annie feel about having an unrelated name?
Not every set of names that shares a nickname feels too close. Amelia and Marianna could both shorten to Mia. Alexander and Natasha might both go by Sasha.
This rule about sibling names mostly applies to the obvious short forms. Bennett and Benjamin, for example.
The harder you have to think about it, the less it becomes a concern.
5. Your favorite sibling names share the same ending.
If you like Isabel, you might also like Annabel.
Ditto names like Parker, Carter, and Harper.
But sharing the same ending is another sign that your favorites might be too close for comfort. In this case, it might not bother your children … but it could make repeating their names together a tongue-twister.
4. They nest like Russian matryoshka dolls.
Does one name fit neatly inside the other? Annika and Julian share an “an” but it isn’t at all obvious.
But Ella and Kellen almost sound like they’re part of the other.
In cases like Anna and Susanna, one sibling’s name is an elaboration of the other.
That can be a little too close for sibling names.
3. They share the same first syllable.
With #10 through #4, it is easy enough to come up with examples that work, despite being close in some ways.
But #3 is tougher to navigate for sibling names.
Imagine sisters named Madeline and Madison? A brother-sister pair called Jordan and Georgia? Twins Miley and Myla?
They’re not impossible, and some cultures prefer sibling names that are as close as possible. But for most families, these feel repetitive.
2. The names rhyme.
Yes, there have surely been twin sisters called Cara and Tara. But most parents – and siblings – would find it a bit too matched.
And yet, this is trickier than it sounds. Timothy and James, Jeffrey and Stephanie and, of course, Benjamin and Jennifer all end up rhyming if you use the most common diminutives.
That means we rule out Emma and Gemma, Hallie and Callie, but also maybe Jonah and Rowan – unless we’re confident they’ll never be called Joe and Row.
1. A combination of the above.
Jackson and Jonathan are close, but probably on the right side of the line. Jack and Sean? Probably fine. Jack and John, though? That inches even closer to the line.
Jeffrey and Stephanie seem less problematic than Benjamin and Jennifer – because the nicknames rhyme and we think of them as a matched pair.
Sarah and Laura are pretty similar as sibling names, but Laura and Maura feel like they cross a line.
So should you choose a different name?
Ultimately, choosing sibling names is completely up to the parents. In most cases, thinking through whether a name is too close is subjective. For everyone who insists that Remy and Romy are way too similar, there’s a family that finds those names exactly right.
This is about testing out your favorites and anticipating problems before you’re holding your newborn in your arms.
What choices have you had to reject because they’re just too close to your an older child’s name?
First published on December 10, 2009, this post was revised and re-published on January 19, 2022 and again on September 7, 2025.
Hello! My name is Amy, and my favorite name for our little girl is Anne. My husband says that he will 100% call her Annie if we name her Anne. I’m concerned that Amy and Annie are way to close, and we will have Mommy & Me names. What are your thoughts? Any name suggestions that are classic and simple like Anne?
Amy and Annie are awfully cute together – for better and for worse. BUT I think you have a big advantage because both names are so solidly familiar. Anne is among the most classic of choices, a name we all recognize and instantly know. Other than asking if it’s spelled with or without an E, it causes little confusion. So that makes up – quite a bit for any possible sense that you’ve chosen matched names.
My only hesitation is what it might mean for future children’s names? If you think this baby completes your family, it’s less of an issue. But if you’re just starting your family, it might feel harder to choose a future name, especially for a daughter. Because while Amy and Annie will only sometimes be said together, siblings’ names are often said as a set (at least during childhood). So would you worry that a daughter named, say, Ruth or Ella would feel left out?
I’ll ask this Q on Facebook, too, and see what others say.
Thank you for you input! I appreciate it!
They’re such established, classic names. I don’t think they would be considered too close. It’s a sweet pairing.
We’re expecting our 9th and she’s a girl. Is Anne or Anna (nicknames Annie) too close to #6 child Andrew (no nickname) who will be 6.5 years older than her? No other repeating initials in our kids.
Congrats! I think there are two factors.
First, when you have a larger family, it’s necessary to relax certain rules. After all, you’re not creating a pattern when there are seven other siblings’ names in the mix.
But, more importantly, Anne/Anna/Annie and Andrew are classic names. We recognize them instantly. That helps a lot. If you had names like Kian and Kiara, it might feel more like they were deliberately matched. But I don’t think it feels that way at all when names have so much history behind them.
I’d use Anna/Anne/Annie for Andrew’s sister without hesitation.
Only name we can agree on is Elliot, but we already have Eleanor and Oliver. Should we go back to drawing board?
What do you think of the names Mila and Miles? I really want to use another M name, but I’m scared they are just too similar!
If they were your only two children – and you felt pretty confident you’d never have to name a third – I’d say it was very, very close – but not unthinkable. Visually they’re almost identical. But mee-lah and mye-ulls … they don’t SOUND quite as close as they appear. But I think I’d look long and hard for an alternative first …
I’m super interested in this topic as we look at naming our 3rd! Realizing how much I’m drawn to similar sounds in names, but ideally avoiding too much matching and rhyming and, even, alliteration.
I have Magnolia nn Magno and Lazarus nn Laz, Lad, or Laddy.
We’re currently loving the girl’s name Gloria. I’m hesitant that the ending is similar and many letters same as Magnolia. Trying to envision how it might work in daily life: would we call her “Glory”? Can you use Ree or Ria without sounding like diarrhea? 😉 Can we avoid “Glo” as a nn as we’ve strictly avoided Maggie thus far (DH dislikes Maggie)?
Also, crossed Thaddeus/Tad off the boy list for rhyming and wondering if Jed (Jedidiah) is too close to Lad.
I’m worried about the Russian matryoshka phenomenon in naming our fourth! We already have an Evangeline (though she is “Evie” 99% of the time). Would Anna sound derivative (or just not as exciting next to her sister’s long name – though we took a turn for the simpler with our boys, Luke and John)? (It’s ok if the answer is yes – our other equally-beloved contender is “Felicity”, which doesn’t run into the same issues!) Thanks for any input! 🙂
It was me, I’d feel left out to be Anna when my sister was Evangeline. I would far, far rather be Felicity.
But … that’s me. Not everyone! And I don’t think they’re particularly mismatched, especially when your boys’ names are more streamlined. And Anna and Evie DO sound perfect together, while Evie and Felicity less so.
If you really do default to Evie – and imagine that’s the way it will be for the foreseeable future – then I’m leaning towards Anna.
Maybe some of it comes down to middles. Evangeline Rose and Anna Felicity feel more balanced than, say, Evangeline Rose and Anna Mae.
Thank you for your comment! That’s quite helpful. If we did go with Anna, we would either go for Anna Felicity or Anna Galilee to her sister’s “long form” Evangeline Grace. Our Evie really is pretty exclusively Evie and is fiercely opinionated whenever referred to as “Evangeline”, so I doubt there’s much chance of her wanting to go by her longer name until middle or high school at least… and I suppose that an Anna Felicity could always transition to her middle name if she wanted a similar style. As an oldest child with three sisters myself, though, I’m sensitive to igniting competition if I can avoid it – so we’ll still have to ponder a bit!
Would Annabelle Felicity work? Then she could go by Anna daily but have a longer name like her big sister.
I’m naming our fourth baby and third girl. Doe you think Saskia (our first daughter) and Astrid (current front-runner) are too similar? we fall Saskia “Sass” and “Sassy” so no doubt we’ll do “Asti” or “Azz/Azz”. Too close???? Our second option is Maeve. Too short? Our other children are Imogen (Immy) and Leo (just Leo!)
Thanks!!
Hmmm … I think Astrid + Saskia are fine, but Sass + Asti? That’s sort of close. And Sassy and Asti sounds VERY close. I don’t think it’s odd to have Maeve with Saskia, Imogen + Leo – they’re great together! But I do like Astrid a lot, so I guess I’m wondering if you’d consider a different nickname. Tridi, maybe? I’m going to ask the FB community if they think Astrid + Saskia are too close, too. Curious to see what others think …
I’m curious what people think about brothers Zane & Ames? We have an Arlo in between so we hadn’t thought of how close Zane & Ames are until today! And I’m due in a few days!
I think it sounds like a great brother set! The rarer “z” sound sets them apart, and all four names have a similar short, modern feel.
Helpful post. We have a daughter Iris and love the name Silas for a boy. Are the endings too similar to work together?
Oh, I love both names. I think I would trip over Iris + Silas. But let me ask the community, because it’s always good to get more than one perspective …
Thanks for this! I am having a hard time naming my soon to arrive baby boy and I am thinking of the name Levi. Do you think thats too close to his sister Isla?
