Zechariah

The Greek for Zechariah is as follows:
Ζαχαρία

I get the impression that Zechariah was the firstborn in his family. The name comes from the same root word as the word "zakar," which means "male." Since every firstborn male in Israel is to be dedicated to the Lord, it would make sense that parents would name their son something that denotes that commandment--that reminds them of their dedication, and of the fact that God remembers their dedication as well.
That's one of the beautiful things about the Hebrew language. It has layer after layer of richness.
