According to Hellin's Law, the approximate frequency for naturally occurring triplets is 1 in every 7,921 births, so that's 0.14%. Even the approximate frequency for naturally occurring twins is just 1.1% (1 in every 89 births).
We seem to get a lot of those 1.1% and 0.14% parents coming on Nameberry don't we?!
I know three sets of triplets. Two were IVF and one natural.
I know a set of triplets called Aliza, Madeline, and Holly. I just think they're great names because they're not matchy, they are all different lengths and they go together as siblings but not super matching styles- there's no theme. My advice would be to pick three distinctly different names that you love and I think you'll be set!
Here are some names that to me are feminine and uncommon but easy to pronounce.
Ones that I think are really close to Vivienne and Cecilia specifically without being too popular would be:
Also both of those names happen to be french, so maybe you are drawn to french names? Here are some you might like that I have not heard much in the Midwest.
Magritte (or the normal spelling Marguerite)
I think stick with what you love so:
Vivienne, Cecilia and Brielle
Vivienne, Cecilia and Sylvia
Vivienne, Cecilia and Althea
Vivienne, Cecilia and Francesca
Vivienne, Cecilia and Odelette
Vivienne, Cecilia and Florence
Vivienne, Cecilia and Gabrielle
Vivienne, Cecilia and Danielle
Vivienne, Cecilia and Evangeline
Vivienne, Cecilia and Genevieve
Jeepers guys...Just read some of the posts. Not sure if talking about premature babies is appropriate! Being pregnant is scary enough. Or have I missed something?!
I would definitely suggest using the Social Security site as a popularity reference - and when you plug in a name, remember that popularity NOW is very, very different than popularity when we were born. In the 80's, the top name was used over 50K times but now, the number one name was only actually used less than 27K times, so basically half the number of babies are given the most popular name now than they were 25 years ago.
At 383, Vivienne is VERY far from popular, I wouldn't worry about that. Cecilia is a tad more popular, but certainly nothing to worry about.
Yeah, I hate to be a stinker, but I don't believe 9 out of 10 stories about multiples that I hear on message boards, I've been frequenting baby name forums since I was 14 and I have only ever come across a handful of anything more than twins that were legit. Twins I DO see more often, but definitely not as often as I see people claim on here.
