Cosima

Cosima, the kind of elegant and exotic name the British upper classes love to use for their daughters, will almost certainly come into wider use here after being chosen by two high-profile celebs in the same month — cool couple Sofia Coppola and Thomas Mars as well as supermodel Claudia Schiffer. It was used earlier by celebrity chef Nigella Lawson, while the male form, Cosimo, was given to the son of Marissa Ribisi and Beck. 

The most famous Cosima in history had strong musical ties--Cosima Wagner was the daughter of composer Franz Liszt and the wife of composer Richard Wagner. Cosima is well used in Germany, Italy and Greece.
