Bennett is Ben with a bow tie, kind of a cross between Benjamin and Beckett. And it's one of the fastest-rising boy names, jumping from Number 362 to Number 194 in the last five years alone--and its choice by "30 Rock"'s Jane Krakowski could shoot it even higher.
Bennett Cerf was an eminent publisher--one of the founders of Random House--and renowned punster.
Bennett is a Top 75 surname, and has many noteworthy bearers, from Jane Austen's Pride and Prejudice family (with one 't') to indomitable singer Tony. Bennett has been used as a surname in England since the early thirteenth century.
