  2. Alaia, 654
  3. Nova, 635
  4. Isla, 500
  5. Haisley, 451
  6. Oaklynn, 406
  7. Kehlani, 387
  8. Ariella, 374
  9. Maeve, 337

Gianna was influenced by the tragic death of Gianna Bryant, daughter of Kobe Bryant.

The girl names that saw the largest increases in usage in terms of relative numbers of babies were…

  7. Alessi, 418%
  8. Eryss, 400%
  9. Gianina, 400%
  10. Giannina, 400%

Some explanations…

  • Ehlani is the daughter of social media influencer Elsy Guevara. (Commenter alex called this one months ago. Here’s Ehlani’s “name reveal” video, from May 2020.)
  • Anayra could be from Anayra Sharma, the baby of Indian comedian/celebrity Kapil Sharma (who has 32 million Instagram followers and 18 million twitter followers).
  • Alessi is the the daughter of Siesta Key cast member Alex Kompothecras.
  • Eryss is the daughter of Love & Hip Hop: Atlanta cast member Erica Dixon.
  • Giannina was a contestant on the reality TV show Love is Blind.

Here are the girl names that debuted most impressively in the 2020 data:

  1. Dalett, debuted with 94 baby girls
  2. Cennet, 84
  3. Ulanni, 44
  4. Souline, 36
  5. Amavi, 30 (this one double-debuted, actually, with 12 boys as well)
  6. Ayzal, 30
  7. Brixleigh, 19
  8. Kazleigh, 19
  9. Yoatzi, 19
  10. Morwenna, 16

Some explanations…

  • Dalett is the third child (born in May, 2020) of Larrymania stars Larry and Kenia Hernandez. (Their older daughters are Daleyza and Dalary.)
  • Cennet is the main character of the Telemundo show Cennet, which looks to be a remake of a Turkish show (Cennet’in Gözyaslari) from a few years earlier. The name means “heaven” in Turkish.
  • Yoatzi is probably from YouTuber Yoatzi Castro.
  • Morwenna might be from the most recent adaptation of Poldark. (Supporting evidence: the name Demelza returned to the data a few years ago.)

The girl names that saw the largest decreases in usage in terms of absolute numbers of babies were…

  1. Harper, decreased by 1,686 babies
  2. Emma, -1,574
