Image via WikipediaIn 2010, the name Angel was listed as the 42nd most popular name parents gave their babies. Although this is a relatively high number, the popularity of Angel has been on a slow but steady decline since it peaked in 2006 at number 30. It's not easy to predict if the decline will persist in 2011. On the one hand, a name that starts declining in popularity will usually continue to do so (at least until it reaches a new plateau), but on the other hand, perhaps the rise in the number of immigrants from South America will keep the name popular in the US.
Angel comes from the Greek word for messenger,
angelos.
It is also worth noting that Angel is somewhat popular for girls in the US, although it has never entered the Top 100 list for girls, and just like it is with boys, the name Angel for girls has been declining in popularity.
