Sister in law using same baby name

Funinthesun20 · 25/03/2025 00:54

My sil has just given birth to my beautiful niece she and my brother have practically named the baby the same as my daughter 7.

Im talking close naming, think Grace/Gracie, Sophia/sophie, Rose/Rosie, Isabel/Isabella, Ella/Ellie….

Now, I know no-one has a right to a name and I know I don’t, that’s not what I’m saying, and I’m not even mad, just really confused! Surly when they were looking at names, they thought that one’s just like our nieces, not that one then? Like my husbands nephew is Theo and we liked Leo, but we thought that’s too close so moved on to other names.

Mine and my family’s reaction probably should have been better. But I was in complete shock when they told her name. I wasn’t rude, but my face said it all!

But the way they (sil and brother) are now acting as if they don’t have a clue why anyone would comment/react. As a lot of people are, as in family friends, wider family, even my work colleagues. Even my daughter is a bit confused “why does the baby have almost the same name as me?”
My mum is now laughing about having to list her grandchildren and say two with practically identical names!

I don’t know the point to this post I’m just…. Venting.

My sister in law did the same her DD with my DS1. Think Daniel Daniela / Michael Michaellla. Then my other sister in law (so both DH’s sisters) almost did the same with her DS2 and my DD, think along lines of Adi Adin (ie same name with a consonant at the end). No one owns a name
and they all have different surnames as DH doesn’t have any brothers. Doesn’t matter.

We have 3 named Jonathan in our small family - 2 by design, 1 by marriage. My husband's mother had 3 named Patricia in herbfamily, again 2 by design 1 by marriage. It's no big deal, you just develop ways of identifying each individual.

BunnyVV · 26/03/2025 17:49

I reckon its
Amelia
Emilia

myladybelle · 26/03/2025 18:15

Meh I have the same (exact same) name as two of my cousins. One on each side of the family believe it or not. It really not an issue. I’m close to one of the cousins we are close to best friends now as adults and just friendly with the other.

wordler · 26/03/2025 18:23

My in laws like using the same names on purpose - it was confusing when I first joined the family. So a lot of parents name their first same sex child after themselves and then if they have another same sex child they’ll use a siblings name - and their siblings are doing the same - so you end up with about three names shared between 12 people.

Cazz1953 · 26/03/2025 18:24

Maybe they really liked your daughter’s name but obviously didn’t want to use it, so chose one like it.

cardboardvillage · 26/03/2025 18:32

It’s bloody stupid. I would not have chosen a name thats already taken by a close family member

Now your parents have two granddaughters with the same name…

Obviously! Doesn’t make it ok though

I think its moronic and shows a huge lack of IQ and imagination.
Nothing you can do about it.

My colleagues SIL did it to her daughter by giving her baby the same name, Alice.
They started referring to her as Baby Al which stuck and pissed off her mother no end.
She was called Ally eventually, but never Alice.
The grandparents thought it was very silly as they lived nearby, same surname, same primary school.
Very silly.

MaddestGranny · 26/03/2025 18:53

DD & SIL chose the same name for their (only) child as that of DD's GodM's (only) DGS. DD & SIL chose the name because easy to spell & sounds same in their two different languages. Realised were 'copying' but +reasons topped
-reasons. There's a 10yr age-diff between the 2 chrn. In the event: GodM; her DD, & DGS were all delighted.

Chn now known as "Big +Name" and "Little+Name", when we're all together. Or, sometimes: "My +Name" and "Your +Name". So as to differentiate who we're speaking about.

Chn are delighted to share a name, and to be "Big" and "Little", it draws them together & has been a bonding thing, rather than anything confusing or detrimental.

I would normally say you’re not being unreasonable. However you used Sophie and Sophia as an example and to me, they sound different. Also, your sister in law may have liked the name prior to you having your daughter? If you aren’t particularly close, she may not even consider that the two close names will be an issue. Perhaps view it as a compliment rather than an insult?

I don’t get what the big deal is.

You named your daughter 7

sasamummy · 26/03/2025 19:18

Years ago when my sis had her first baby, and the first grandchild in the family, I flew over from abroad to see her. She couldn't decide on a name and so I went out and bought a baby name book from WH Smith that cost me a bomb - using my last English tenner.
I flew home a few days later and she rang to say they had given the baby the same name as me, but she also pointed out that it wasn't after me or a tribute of any kind! Um, thanks then. I was pretty miffed on many levels for a while but we are two very different people - people know that too and you soon get used to it. Take a deep breath, don't overthink it (and maybe be a tad smug you got in there first... LOL).

pollymere · 26/03/2025 19:20

I get why you feel narked. It's seriously lacking in originality. You have my sympathy.

Messycoo · 26/03/2025 19:43

I totally get it , just why? seems inconsiderate to me .
My Godson has a daughter
and then his half sister named her daughter the actually same name ? The girls are only a few months apart in age. Although the saving grace is their live on different continents. GP’s having two GD’s with the same name! Weird situ. I think we all want to feel our names separate us from others and I see it’s why we have different names . Take it as a compliment .

Blueberrypot · 26/03/2025 20:00

If I was them, I’d solve by having nothing to do with you. Especially as you are the in-laws. Problem solved.
I have a cousin the same name couldn’t care less.

SirDanielBrackley · 26/03/2025 20:29

Who cares?

auderesperare · 26/03/2025 20:49

I have said it before and will say it again. My husband has seven (7!) first cousins on his mother’s side with the same first name as him. (Most also have the same surname). There are also 3 aunts and a cousin with the same first name. Farming family. Everyone named after the grandfather who had 8 kids by two wives. Seating plan at the wedding was a nightmare.

Low IQ? What a peculiar thing to deduce.

Gambit1977 · 26/03/2025 22:15

You don’t own
the name my brother gave his daughter same middle name as my daughter it doesn’t bother me and I named my son the same name as my ex brother in law and he’s cool with it and my cousin named her daughter the same name as me never bothered my parents it’s just a name

If you and your DH are the only link then surely it’s only you or your DH that would mention one of them and the other one of you not know who was being referred to, so come up with your own personal method to differentiate?

Otherwise assume if someone in your family mentions the name they mean the one in your family, and if someone in DH’s family mentions the name they mean the one in DH’s family?

Agree. It only causes problems in my own household. We constantly have to say things like, X, the one on your dad’s side, is doing …. Or Y, the one on my side, is ….

I don’t fault them because we are the only link. Just illustrating how it is annoying and would be a problem within a family.

Hankunamatata · 26/03/2025 22:24

Some are coler than others Sophie and Sophia isn't too bad, same with Ella and Ellie.
Really depends on the name

I call my son a nick name using his name

Is his name Nicholas...?

My BIL and his wife chose our yd’s names for their first daughter only spelt slightly different - Molly May Rose and Mollie Mae Rose. They asked what I thought whilst sneering at me (they hate me bc I’m not religious) so I said I didn’t care that they were so inept that they couldn’t think of their own names but I was sad for their daughter that she was given that name out of spite. Smiles faded and they changed her name.
