Eliana is a lilting, rhythmic choice, which has caught on in the US and other English-speaking countries, along with many other El-starting names.
 
The Hebrew name Eliana was taken from the elements el, meaning "God" and ana, meaning "answered." Eliana also has roots as a variation of the Late Latin name Aeliana, a feminization of the male given name Aelianus, itself derived from the Roman family name Aelius. Aelius is related to the Greek word helios, which refers to the Sun.
 A widely multi-cultural choice, Eliana is heard in Israel, Spain, Portugal, Russia and Italy. The pretty French version is Eliane.
 One celebrity who chose it for his daughter is Christian Slater.

Samuel has been so popular for so long that it's hard to believe it's still climbing, at its highest point since the 1890s. 
 
This biblical name's popularity is somewhat propelled by the likability of the friendly nickname Sam, which returned to favor along with fellow former Grandpa names like Max and Gus. Sam is now often used on its own, for girls as well as boys.
 Samuel is derived from the Hebrew name Shemu’el, meaning "told by God." In the Old Testament, Samuel was one of the great judges and prophets of the Israelites, destined for a holy life from birth. He established the Hebrew monarchy, anointing both Saul and David as kings.
 
High-profile celebs who have chosen Samuel for their sons include Jennifer Garner and Ben Affleck, Jack Black, and Naomi Watts and Liev Schreiber, and Keri Russell and Matthew Rhys.

Zachary, a Top 20 name throughout the 90s, is now sliding down the rankings though it remains in the Top 200. With its ancient roots and modern feel, it's easy to understand why Zachary has been such a longtime winner. 
 
Zachary is the English variation of Zacharias, which itself is derived from the Hebrew name Zechariah. The name Zachary is attached to eight different people in the Bible, the most prominent being the father of John the Baptist, and it's also presidential, via 12th president Zachary Taylor. Zackery is an alternate spelling, and nicknames include Zack, Zach, Zac, and Zak.
 
Sir Elton John chose Zachary for his long-awaited first child, which may help propel it back into the spotlight. But contemporary parents might want to keep looking for more original alternatives. Variations such as Zachariah and Zacharias may have longer beards but at the same time feel fresher, while other Z names—from Zebedee to Zane—may suit parents whose main attraction is to the initial Z. 
 
Several of today's prominent Zacharys go by short forms—Zac Hanson, Zac Efron, Zach Galifianakis, Zach Braff and designer Zac Posen.
