Matt Grant had a link to this on his talent blog: the Baby Name Wizard. Superb live graphics as you search for how popular names were at any given time over the past 100+ years. A great thing to play around with for a few minutes (and check your own names, of course). Andrew peaked in the early 1980s at over 7000 kids per million babies, as did Jonathan, my middle name, that J in my blog address.
Miles just reached 400 kids per million babies. It's never been as popular before. Luisa stopped being used in the US in 1930! Sara also peaked in the early 1980s. In fact, so did Andrea. Even Andrea as a boy's name peaked around the same time. So with the exception of Miles, we are the family of outmoded names. :-)
