I do not personally have “rules” in regard to my choice of names or my children’s own sibset. I chose what I liked and that was it. However, when a friend veers from a started course, I notice it. For example:
[name]Charlie[/name], [name]Cate[/name] and … [name]Marie[/name]
[name]Ava[/name], [name]Allie[/name] and … [name]Samantha[/name]
[name]Brett[/name], [name]Brooke[/name] and … [name]Samantha[/name]
[name]Julia[/name], [name]Jack[/name] and … [name]Rosie[/name] (family names so maybe a little leeway?!)
[name]Kate[/name], [name]Caroline[/name], [name]Charlie[/name] and … [name]Jack[/name]
Not that it matters what any of us think but would you feel left out if you were the other letter?!
I notice the difference here but I’m a little bit of a freak when it comes to same letters for siblings, e.g. I adore [name]Aubrey[/name], [name]Addison[/name], [name]Avery[/name], [name]August[/name] and [name]Asher[/name] but I’m struggling have 2 A names on my top 10 lol.
I’d like to think that I wouldn’t feel left out and that my parents had given me a name that they loved. I mean this is a little bit different but me and one of my brothers have family middle names but my other brother doesn’t and he doesn’t feel left out at all. I think it would be something that would bother you in the younger years but as you got older it wouldn’t really mater.
I think as long as the sibset matches it isn’t too bad, but [name]Ava[/name], [name]Allie[/name] and [name]Samantha[/name] seems really odd.
I hate reading about sibset rules. It drives me nuts. It bothers me because people have restricted themselves so much they can’t even find anything they love on their own, or they pick something they don’t even like just to follow a theme. WHY would someone pick a name they don’t even care for? Doesn’t make any sense to me.
My brothers’ names start with the same first letter, and it doesn’t even register with me. My parents didn’t do it to not include me (I was also the first-born), my youngest brother was actually named with a C name for a could hours and then me and my other brother told our parents, “Nope, his name is B____” and we convinced them over the phone to change his name. I was 6 at the time, very in-tune with the spellings of names, and I never felt as though I was somehow ‘left out’ by not having a B name. It didn’t even register that I was the different one (or that it’s seen as being such a weird, negative thing)
I know a lot of families that have 2 kids out of 3 whose names start with the same letter. It’s fairly normal. I don’t think 2 names in a sibset of 3 is a pattern or a rule or a theme, it’s a coincidence. With a coincidence, I don’t see the downside of naming a 3rd child with a different starting letter. The parents will still be able to say, “We love all your names very much” rather than, “I love the first two’s names, and you, third child… well, I don’t like your name but it matched so we absently picked it.”
I know a sibset where the oldest daughter has an R name and the boy and the younger girl have J names. I don’t think it really matters on the letter if they’re all in tune stylistically, I’d be more bothered that [name]Ayden[/name], [name]Ashlee[/name] and [name]Clementine[/name] don’t seem like a sibset, two trendy and then one unique, than I would that [name]Clementine[/name]'s name doesn’t begin with an A, if you get what I mean. I think it’s fairly normal to have sibsets with some the same letter but not all, and at least it’s not like the Duggars where you’re just spooning around for a J name to fit rather than going with the K or P name that you absolutely adore.
@essjay - I always think of the Duggars when this question is brought up. Is it wrong that I secretly hope [name]Michelle[/name] will stick it to [name]Jim[/name] [name]Bob[/name] on the last baby and name it something starting with an M? :twisted: I mean, really, they’re going to be down to Jello and Jehoshaphat soon.
Aaanyway… both DH’s and my families are/were like this. The sibset is [name]Jeffrey[/name], [name]Jonathan[/name], and [name]Timothy[/name] (DH). I honestly don’t think he ever noticed until we met in college and I pointed it out, so obviously he wasn’t up nights fretting about it 
There was a large age gap between [name]Jeff[/name] and [name]Jon[/name] and a huge religious… umm… awakening? I have three MUCH (12+ years) older half brothers, [name]Scott[/name], [name]Stephen[/name], & [name]Timothy[/name]. I seriously doubt [name]Tim[/name] ever noticed. Those boys had much better things to bicker about.
I know tons of sibsets like this, TBH, and while they tend to stick out to me, I don’t think they’ve ever caused a problem for the kids.
In my own naming, I think I’ll be much more paranoid about clashing/repeating vowel sounds or endings than same letter. However, we’ll probably only have 3 kids max, so I don’t imagine it will be too difficult to avoid two of the same letter. Two names can start with the same letter and still be very distinct sounding, you know? Or start completely differently but be way too close for comfort.
That’s my two cents!
To me, they just have to have the same “feel.” For example, I wouldn’t have this sibset:
[name]Cordelia[/name], [name]Persephone[/name], [name]Isadora[/name] and…[name]Jane[/name]. [name]Jane[/name] would feel slighted for getting an one-syllable no-nonsense name while her sisters got frillier, princessy names.
I also wouldn’t do:
[name]James[/name], [name]Oliver[/name] and…[name]Ayden[/name]. Pretty self-explanatory there.
I don’t mind when two names start with the same letter and a third doesnt…maybe if it was 7 with the same letter and one without I’d be more likely to raise an eyebrow. I have more of an issue with [name]Caroline[/name] and [name]Charlie[/name] in the same sibset because [name]Caroline[/name] is the fem form of [name]Charles[/name]…
My only big “rule” for sibsets, is if you start using unisex names for girls, I think you should try to avoid the next girl having a very frilly name, either have [name]Amelia[/name] & [name]Sophia[/name] or have [name]Piper[/name] & [name]Harper[/name]…but it sort of compounds the confusion otherwise (If I saw a sibset of [name]Michael[/name], [name]Ryan[/name], & [name]Martha[/name] and a sibset of [name]Quinn[/name], [name]Felicity[/name], and [name]Elizabeth[/name] for example…I’d assume [name]Ryan[/name] and [name]Quinn[/name] were boys)
[name]Caroline[/name] isn’t a feminine form of [name]Charles[/name]. You are thinking of [name]Charlotte[/name]. [name]Caroline[/name] is a feminine form of [name]Carolus[/name], a name that is hardly used.
Ha! Oh thank you, I needed a laugh this morning…poor little Jello Duggar.
I think in some cases it’s bother me, like [name]Charlie[/name], [name]Cate[/name] and [name]Marie[/name]. If you just HAD to spell [name]Cate[/name] with a C, why go to an M name after that?
I know a family with two kid, boy and girl, both have H names. They’re expecting a girl, and are likely going to name her [name]Mia[/name].
But like PPs mentioned, it bother me more when the styles are so off.
Isn’t [name]Carolus[/name] the Latin form of [name]Charles[/name]? To my knowledge they’re all the same family of names ([name]Carl[/name], [name]Carolus[/name], [name]Carol[/name], [name]Carlos[/name], [name]Charles[/name], [name]Charlotte[/name], [name]Charlene[/name], etc). My name is [name]Caroline[/name] and it was a family name originally used to honor a [name]Charles[/name] so I guess that’s how I associate it.
I don’t see anything wrong with the names. I am just weird though I guess. Maybe I would notice if the daughters were [name]Henrietta[/name] and Kynsey or Amariyanna. I would think, wow [name]Henrietta[/name] has such a pretty name but her sisters have such different names (nothing against Kynsey or Amariyanna).
I don’t think these sibling sets had to stick with the C or B theme. Two kids don’t make a theme to me. Maybe three or four children, but not two. I am weird though. 
You are right. My apologies!
For me it’s more important that they fit with a similar style. I don’t think it has to be that exact, but I do, think it would be odd to see siblings named [name]Caroline[/name], [name]Elizabeth[/name], and [name]Neveah[/name], for example. Having two names that start with the same letter and a third that starts with a different letter doesn’t bother me. I don’t think there’s enough kids to be starting a theme yet. I suppose if there were seven of them all starting with the same letter, the 8th kid might feel left out if his/her name was different. But who knows. Maybe they’d appreciate it at this point!
But, generally, I don’t think it’s a big deal. I think my name and my sisters’ names sound pretty together but it’s not too often that I hear them said together (except by my parents) now that we are adults. I wanted my daughter’s names to sound nice together, but I also liked names that were of a similar style … so I was always picking a name that I liked.
[name]Carolus[/name] is a form of [name]Charles[/name] so technically it is though I think you’re right that [name]Charlotte[/name] is the closest feminine form of [name]Charles[/name].
