From the experts:
When Jennifer was ready to give up her throne, her crown was passed to Jessica, who reigned for not one but two decades; Jessica was the top name of both the 1980's and 90's, never sounding quite as trendy as its predecessor, maybe because of its classic Shakespearean pedigree. Jessica has declined a bit in popularity but is still a popular choice.
Jessica seems to have been coined by Shakespeare for the character of Shylock's daughter in The Merchant of Venice, possibly as a form of a biblical name. There are several attractive Jessicas on the scene today, including Jessica Lange, Jessica Alba, Jessica Biel, Jessica Simpson, and Jessica Chastain.
