Yes, I did 😛 and obviously it is ^^ nice thread for it in the questions-forum 😛
What does it mean?
Good question.
Actually, I have no idea.
It's an Anglo-Saxon name... I chose it because it was the name of a woman in a book I recently read, The Burning Man by Tad Williams, she is the wife of a certain Lord Sulis, also called the Heron King, of Osten Ard... I somehow liked her character in the book, she wasn't really important, but her story kinda sad... I tried to find out a little more about the real person who gave the name for her, the historical Cynethryth (or Cyneðryþ) was the wife of the King of Mercia; some scientists think they're the same as Arthur and Guinevre (their names sound both pretty the same when pronounced), but this meaning wasn't really my intention... I just liked the name 😛
