Do you want your kids to have names that go well together?

Depends how you mean. I wouldn't want rhyming or very obviously matching names (Noel and Liam, say) but it might be odd if they're very obviously different styles of names.

I worked for a while in the US and had a colleague who had two children with very religious names, and then one very modern. Like Caleb, Elijah and Dixie-May. There was another who'd had a big age gap between their first three children and their fourth and had had something of a lifestyle/image change in between. (Performative hippies). It was something like James, Zoe, Emma and Phoenix.

Mmm

My dc have one very 70s and one very 00s name (e.g. Nicola and Oliver, David and Lily) and I do feel a bit weird about it sometimes. The 70s name is quite out there for a baby and the 00s name is supremely ordinary (but beautiful!) And I feel like people who assumed I was quirky for dc1 now think I just have no taste.

They are both family names and very meaningful to us but sometimes I wish they went together better.

It wasn't the be all amd end all, but I didn't wang the names to sound completely discordant, or too similar - e.g. Oliver and Olivia.

I suppose following my example, my brother is David so a name like Rebecca or Rachel would have gone a bit better. Not a big deal but it is a bit weird!

Absolutely. Because they're both individuals and a sibling team. It doesn't really matter in life of course, but I always find it so weird when I come across siblings with such differing types of names.
I also like names to look equally nice written down, but then I am weird with stuff like that.

Like pps have said, I think sibling names make more sense when they all have a similar vibe/are of a similar naming style. I don’t like twee rhyming or matching names.

Blake Lively and Ryan Reynolds have 3 daughters called James, Inez and Betty. I’m unreasonably bothered by how these three names are all from completely different naming styles.

Sometimes I hear sibling names and think, oh, DM got to name one and DF got to name the other as the names don't seem to go

Like Hannah and Aishling
Like Grace and Áine (which if they went to a Gaelscoil would be Gráinne and Áine - grawn-ya and awn-ya)
Like Aoife, Ciara, Orla and Grace
Like my 3 brothers who got lovely Irish names and me, who got lumbered with my aunt's old fashioned English name

But better to be distinct than matchy-matchy, better to have different initials too

We just chose names we liked. I named DD1, who has a name of Irish origin, and my husband chose the name for DD2, who has a name of Hebrew origin which is more popular in Europe than in the UK. They actually work well together as neither is 'out there'.

Yes. I don't know why 🤷🏻‍♀️

No and I find it icky when they do. Sounds odd and why would you? Just choose names you like for each individual. They are their own person.

I must admit my mum gave my brother a name that was quite popular in the 70s/80s - sort of 80s equivalent of Oliver - and gave me an obscure Welsh name which isn’t even particularly popular in wales and I do find it a bit tiresome.

Tilly, Millie and Josephine.
Had they been Matilda, Millicent and Josephine or Tilly, Millie and Josie, they would have seemed more of a similar style

Yes I think they need to ‘work’

One having a really unusual and one a super common is a tad strange, or they might wonder why

James and Charlie - fine
James and Charles - fine
JJ and Charlie - fine
JJ and Charles - weird

Growing up I went to school with triplets. Tilly, Millie and Josephine. Just seemed odd.

We just chose names we liked, I think unless your taste in names is very very varied then if you like the names they should work together ok. I did avoid names with starting with the same letter though.

I just picked names I liked. I do think they sound good together but it wasn’t part of my criteria when choosing.

I’m not really a fan of themes or matcy names but quite a lot of people I know with kids are

Ideally they would sound good together - I worked with sisters one had a quite posh name, the other very hippie, the names didn't suit as a pair. However, if I loved each name independently I wouldn't be put off, finding names that both parents agree on can be hard enough without other hurdles which ultimately don't mean anything.

I would, however, be mindful of trying to keep a similar level of 'normal'. I wouldn't have Konstantin and James - James might feel put out his name is boring in comparison, or Konstantin might think he drew the sort straw being more out there. I feel James and Frank, or Konstantin and Lucien work much better in that respect.

A much bigger concern for me is not having names that match, but not having them too similar - either sonically like Clara and Claudia, or from the same name root like Alex and Sacha.

Yes 100%
I think it's odd not to

So I wouldn't call one John and the other River for example. Or Joe and Wolf

Or I wouldn't go for Ethan, Bradley and then have a Josephine.

Or Charlotte, Elizabeth and then call the last child Aoife or Seamus.

Likewise I wouldn't go Aoife, Ciara, Niamh and Louisa. They don't match.

I just think it sounds discordant. My DH doesn't agree. Though our DCs names are the same kind of "vibe"
