Ricky Ponting and his wife called their new daughter Matisse. I think it is very pretty.

My DD is called Tara and if one of my twins was going to be a girl we were going to use Eliza. I also liked the name Poppy but my DH didn't like it at all.

As for trying to be french, I wouldn't worry about that. All my kids have Irish/Celtic names - including surname - Tara, Rhys & Liam and my name is Irish as well but we are all true blue Aussies. If you love it then go for it
