Actually, Ms. Chrisell, the name
Harmony is an adaption from the name
Harmonia, which in Greek, was a princess and the daughter of
Aphrodite and
Ares, and the wife of Cadmus. In Latin, harmonia was a word with several different meanings. I am a linguist and a historian and I believe I know what I am talking about.
Nicole has been used for quite awhile in many forms, such as
Nicholas and
Nicolette. And I also believe what this lady wants to know is the actual history of the name, not how popular it is.
