Of the 1,204 girl names bestowed last year, 811 (67%) were used just once. A smaller proportion of the 919 boy names — 549 (60%) — were bestowed once. Here are a few of those single-use names:
| Unique girl names | Unique boy names |
| Amarilla, Antimony, Edelweiss, Ember, Fanny, Lluvia, Lovely Estrella, Mae Pearl, Magnolia, Nkirote, Reminisce, Rosalene, Rurapenthe,* Summit | Attimus, Banyan, Cypress, Cyprus, Destry, Ernestor, Fogatia, Iknav, Montgomery, Mercury, Orion, Quintil, Thornhill, Zinley |
*Looks like Rurapenthe is based on “Rura Penthe,” the name of a planetoid used as a Klingon penal colony (!) in the Star Trek universe. Its name is a nod to Rorapandi, a penal colony island in the Disney movie 20,000 Leagues Under the Sea (1954). Rorapandi was invented by Disney; it did not appear in the Jules Verne novel Twenty Thousand Leagues Under the Sea (1870).
