Gianna
Gianna -- a Latin feminization of John -- is rapidly gaining favor outside the confines of Italian culture; Gianna is now among the Top 100 in the U.S., at Number 73.
This common Italian classic entered the US list in 1989, breaking into the Top 100 in 2006, along with other such stalwarts. Basketball star Kobe Bryant has a daughter named Gianna.
Also on the US list are Giovanna, Giana and short-form Gia, which was used by Matt Damon and Mario Lopez.
