My Favorite Names

The origin of the name Aaron is debated—some say it was derived from Hebrew, while others claim it originated in Ancient Egypt. In the Old Testament, Aaron, the older brother of Moses who was appointed by God to be his brother's spokesman, was the first High Priest of the Israelites. The Hebrew version is Aharon—in Yiddish it can be Aaran—and the name appears in Arabic as Haroun or Harun.

Widely used here since the fifties, Allison -- a derivative of Alice -- has now been once again surpassed by the original Alice as parents embrace vintage revivals. Despite this, Allison's popularity has held strong, and it remains steadily within the Top 100. Allison's status is challenged by up-and-coming "-son" names, from Addison to Emerson. The freshest Allison alternative may be Ellison, which adds the appeal of trendy nickname Ellie as opposed to falling nickname Allie.

Does Fay really need that e at the end? We vote no, but modern parents disagree: The Faye spelling was used for nearly 300 girls in 2014, vaulting the name back onto the Top 1000 after a 35-year absence, nearly ten times as many babies as received the Fay spelling.

Isaac has shaved off his biblical beard and leaped into the upper echelon of popular boys' names, outrunning cousin Isaiah. A favorite of the Puritans, Isaac has never dipped below Number 400 on the US list of top boy names.

Katherine is one of the oldest, most diverse, and all-around best names: it's powerful, feminine, royal, saintly, classic, popular, and adaptable. Long one of the top girls' names starting with K, Katherine has now been unseated on the popularity list by upstarts Kennedy and Kinsley, but a dip in popularity only adds to its charm.
