Jessica seems to be popular every generation so I'd say it's pretty timeless. I personally couldn't use it as I know too many Jessica's my own age. There are not a lot of names this happens with- names seem to usually skip a few generations and a lot names being used now are the names of my grandparents generation. I thought Jessica was pretty popular at the moment, but storm is probably right that that was more so a few years ago. As everyone has said- if you love it go for it!
