Alyssa was in the Top 20 from 1997-2010 and peaked as the 11th most popular girls’ name in 1998 and 1999 but has become less popular in recent years. It's related to the flower alyssum as well as to the classic Alice and variants. Alyssa Milano helped give it a bounce back when she was still a child sitcom star.

Kendra was once seen as a feminization of Kenneth -- but it's now firmly established as a standalone. American parents can't seem to make up their mind about it though: it was one of 2013's fastest-rising names, entering the Top 200 for the first time since 2000, but then it tumbled again.

Angel is one of those names that has a very different trajectory for girls and boys. As a female name, it was most popular in the US from the 1970s until the turn of this century, almost breaking into the Top 100 at its peak in 2001 but then beginning a long slide down the list.
