The only
Cosima that I had ever heard of in real life was
Claus and
Sunny von Bulow's dd. I associated it with the ultra-rich and / or Europeans.
I'd love for
Cosima to become more widely used here in teh U.S. I find it gorgeous to say and to hear. I've worried in the past that people would mispronounce it as "co-SEE-muh." But if it does get more popular then that will become less of a factor. I odn't know about it becoming "big." Just becoming better known is all that I ask for.
