"Jessica first appeared in the Shakespeare's 'Merchant of Venice' and her origins are much debated. It is possible that Jessica comes from the Hebrew name found in the Bible as Iscah, which was translated in Shakespeare's time as Jesca.
Having shown amazing popularity in the US from the late 70s to the late 90s, Jessica fell to 32nd place in the US charts in 2006. However, in 2007 it was the fifth most popular name in the UK, having held the top spot in 2005. Jessica is also currently in the top 10 of all the Australian states, and New Zealand."
However, "Jesseca" itself is a rarely used name, making the person who has it a very unique (and amazing) person.
It is also said that babies with this name will hold a lucky and loving life. They will be cherished by the people closest to them, and those friendships will tend to last for years on end with few regrets.
Common nicknames are- Jess and Jessi
