Interesting one-hit wonder names in the U.S. baby name data

single flower

They came, they went, and they never came back!

These baby names are one-hit wonders in the U.S. baby name data. That is, they’ve only popped up once, ever, in the entire dataset of U.S. baby names (which accounts for all names given to at least 5 U.S. babies per year since 1880).

There are thousands of one-hit wonders in the dataset, but the names below have interesting stories behind their single appearance, so these are the one-hits I’m writing specific posts about. Just click on a name to read more.

Glitch alert: Why are there truncated names in the 1989 U.S. baby name data?

glitch

While doing some name research recently, I noticed a whole bunch of typos like “Christop” and “Alexandr” among the top 1,000 U.S. baby names of 1989.

I figured all the typos must be coming from a single source, so I checked the SSA’s state-by-state data, starting with the larger states. Didn’t see anything in California, didn’t see anything in Texas…but then I checked New York, and there they were:

Name# in U.S.# in NY% in NY
Christop (m)1,082*†1,082100%
Christin (f)926†49954%
Stephani (f)636†48977%
Elizabet (f)445†41994%
Alexandr (f)301*†301100%
Alexande (m)301†29999%
Katherin (f)277†24890%
*Debut, †Peak usage

A few of the above may not be typos, but the fact that so many are concentrated in a single place suggests that most are.

Given the time period and consistent truncation, my guess is that one of the counties in New York started using a computer system in 1989 that only allowed the input of up to 8 characters per name.

Now the big question: Did this glitch skew the national baby name rankings?

Yes, but only for Alexandra:

Name(s)# in U.S.Rank in U.S.
Alexandra (f)7,67943rd (old)
Alexandra (f) + Alexandr (f)7,98041st (new)

All 301 of the baby girls named Alexandr were born in New York, so it’s likely that all of them are typos. If we add these 301 to the total for Alexandra, the new number nudges Alexandra up two spots to #41. (This would bump the names Brittney and Hannah down one spot each.)

UPDATE, Apr. 2020: I recently combed through the rest of the 1989 baby name data and found even more typos:

Name# in U.S.# in NY% in NY
Jacqueli (f)157*†157100%
Cassandr (f)152*†152100%
Gabriell (f)144†11580%
Christia (m)82*†8098%
Nathanie (m)58†5595%
Elisabet (f)51†2549%
Jacquely (f)50*†4794%
Kristoph (m)44*44100%
Mackenzi (f)422662%
Salvator (m)41†3790%
Johnatha (m)34†3191%
Katharin (f)23†23100%
Anastasi (f)22*†2091%
Francesc (f)19*†19100%
Kimberle (f)171271%
Dominiqu (f)15*†15100%
Nicolett (f)15*1280%
Annemari (f)14*†1393%
Kassandr (f)13*†13100%
Johnatho (m)12*†12100%
Mackenzi (m)11*†982%
Sebastia (m)11*†11100%
Bernadet (f)9*†9100%
Demetriu (m)9*†9100%
Geneviev (f)9*†9100%
Kristofe (m)9*†9100%
Alejandr (m)8*†675%
Antoinet (f)8*†8100%
Cassondr (f)8*†8100%
Constanc (f)8*†8100%
Francisc (m)8*†788%
Priscill (f)7*†7100%
Annamari (f)6*†6100%
Angeliqu (f)5*†5100%
Francesc (m)55100%
*Debut, †Peak usage

Many of the above were one-hit wonders, which makes sense.

P.S. Here are three more glitches I’ve found since writing this post: the Korea/Kansas mis-codes, the New York state data gaps, and Essfa in Vermont.
