It made its first appearance in the US Top 1000 in 2016, when it was the third-fastest-rising girls' name.

More commonly seen here as Anya, this traditional yet unique Irish name belonged to the queen of the Munster fairies and is sprinkled throughout Irish folklore as an early Celtic goddess of summer and prosperity.

No, the pronunciation--ro-SHEEN--isn't immediately obvious to the non-Gaelic viewer, but the sound of this shiny Irish version of Rose is pretty enough to make it worth considering.

Orfhlaith is a traditional feminine Irish name with ancient Gaelic origins, pronounced approximately as 'OR-la' or 'OR-lah.' It derives from the Gaelic elements 'or' meaning 'gold' and 'flaith' meaning 'princess' or 'sovereignty,' thus translating to 'golden princess' or 'golden lady.' This name dates back to medieval Ireland and was borne by several noble women in Irish history. While the original spelling Orfhlaith remains rare outside Ireland, its modernized form Orla has gained more international recognition. The name connects deeply to Irish heritage and Celtic traditions. Despite its challenging spelling for non-Irish speakers, it carries a sense of historical dignity and cultural richness that appeals to those with Irish ancestry or appreciation for Celtic heritage.
