Have a look at the Turkish Deren, the Basque Nerea, and the Sanskrit Sonali for a start. Lots of international girl names are highly unique in the English-speaking world. What are the most unique girl names in the world? One-of-a-kind names you create yourself probably qualify. These include Blue, Banks, Eleven, Venus, and Winslet. Rare girl names with celebrity ties also have a better-than-average chance of becoming, well, less unique. Along with Birdie and Bee, cute unique girl names with nature meanings include Fleur, Lilac, Posey, and Snow. Unique nature names for girls seem to be especially primed to rise in popularity. Some people might also define unique names as those that are new and different from traditional names. By rare, unusual, and uncommon girl names, we mean names that don't rank in the Top 100 or even the Top 1000 in most countries, which makes these girl names uncommon no matter where you live.
