Chloe and Daniel are out! Elizabeth and Liam are in! At least, as far as Social Security's Top 10 lists of the most popular baby names for boys and girls in 2012. Among the boys, Jacob remains at the top of the list. It's held that spot since 1999, which is a good indication that there are a lot of Jacobs and Jakes in this country. Sophia is the top pick for last year's baby girls. In fact, six of the top ten girls names end in A, which suggests an ongoing trend there.
