Francesca is also a fairly common name in the UK. According to one of my name books (Llewellyn's Complete Book of Names by K. M. Sheard) Francesca was originally introduced to the UK by the 1945 British film The Seventh Veil, in which the heroine is called Francesca Cunningham. It's usually pronounced fran-CHES-kÉ™ here, which is an approximation of how it is said in Italian.
