Hannah is one of the nation's top biblical girls' names — it surpassed Sarah in 1998, and ranks in the Top 100 along with Elizabeth, Abigail, Chloe, and Naomi. Hannah is a name with many sources of appeal: Old Testament roots, soft and gentle sound, and a homey yet aristocratic image.

Aaron is a name of subtle contrasts: an unusual spelling that is easily recognizable; a solid Biblical choice that doesn’t feel exclusively tied to religion; a well-established name for boys but sometimes confused with the girls’ name, Erin; used internationally but with notably different pronunciations; classic like Andrew but not out of place with recent favorites like Weston or Jayden.

This biblical name is getting wider notice. While Adrian has had its time in the limelight since the late 70s, parents are beginning to look for fresher alternatives.

The angel Adriel is known as the Angel of Death. Adriel entered the charts in 2002, and has risen now into the Top 200.
