Farah is a soft and lovely Arabic name, best known here in this original spelling via the last Empress of Iran, Farah Palavi. It's currently a Top 250 name in both France and the Netherlands, which both have a large Arabic-speaking population, and appears in at least two video games.
The variant spelling Farrah had a brief moment of popularity when Farrah Fawcett burst onto the scene in Charlie's Angels in 1976: her name shot up to Number 177 the following year, and after many years off the charts, it's back at Number 780 thanks to a Teen Mom named Farrah. Farrah Fawcett claimed that her mother made up the name because she thought it went well with their surname.
