Cosima, the kind of elegant and unusual name the British upper classes love to use for their daughters, is given to a handful of baby girls in the US 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.
