I thought that this was a brilliant little java applet that allows you to examine the popularity of names over time. Not surprisingly, many of the biblical based names remain at a somewhat steady stream of popularity and that some names tend to come and go based upon television or movie characters having those names.
My name appears to have been most popular in the 30s and 40s and has been in decline since. Suits me.
It also demonstrates a frightening trend of late to have children named after product brands.
