Be careful though. Many names on the top 20 list for the past few years (for girls) are names that were popular 70-80 years ago.
So you may find that your kids' names become popular again.
I don't care if they become popular a few years after I use them; That makes me a visionary trendsetter. :-)
I just don't want them to be one of twenty 'Gavins' of the same age.
