I had no idea that a tarn was a thing and now I know it is!
Interesting name. Something about it seems familiar in a nice way. I'm not sure about it for a girl (if I was Tarn's mom I probably would have gone with the safer
Corrie), but I do like it. I also like the Scandinavian words for a tarn - Tjørn, Tjörn and Tjärn. Now those are some cool words.
Tarn
Harry popped into my mind as a combo right away. There's something smiley about that combo, I quite like that.
