Oooh, I love
Jeanne. It would be so nice to see it used again, especially as a fn. And if it's a family name for you then all the better.
I'm with you on the pronunciation. Either like
Jean or the French way, "zhan." My only fear with
Jeanne is that a lot of people (here in the U.S.) think it should be pronounced like
Jeanie. I love
Jeanie, but not spelled "
Jeanne."
