How Names Spread

This website is pretty sweet. It shows you the regional demographics and popularity of a name over the years. Here is a link explaining how it works. Audra isn't the most popular name, so it isn't on many lists and it was nice to see some real info on it. It is a lot older of a name then I expected, which just makes me love it more.
