Orla is an Irish name closely associated with the high king Brian Boru, as it was the name of his sister, daughter and niece. It was very popular in the Middle Ages – the fourth most popular name in twelfth century Ireland – and has become popular again in Ireland, Scotland, England and Wales today. In Irish, the name is commonly spelled Orlaith or Orlagh.

Gentle giant Rubeus Hagrid is the groundskeeper at Hogwarts in the Harry Potter novels (probably after Hagrid Rubes, the equally kind ancient Greek mythological giant), but that's not the only reason this name could prove a playground liability.
