Two famous bearers of this name are the Finnish president, Tarja Halonen, and also the famous Finnish opera singer Tarja Turunen, who also sings in the metal band Nightwish.
Tarja is the name of the operatic vocalist of progressive/speed metal band Nightwish. She is very beautiful and her voice is nothing short of lovely. :)
This is a very pretty name, I always thought it was pronounced with a soft 'j' sound like in French, but 'ta-re-ah' sounds very nice too. I think you can tell from the amount of similar posts on this page who the most famous bearer of this name is. :P
