Xavier originated is use as a given name after Saint Francis Xavier, cofounder of the Jesuit order, who got his name from the Spanish-Basque village where he was born. His birthplace was Javier, the name of which was derived from the Basque place name Etxeberria, meaning "castle" or "new house." Many Americans pronounce the initial X, as in ex-ZAY-vee-er, but it's equally accepted to pronounce the name ZAY-vee-er, closer to the French pronunciation.

Both Jair and Yair have been in and out of the US Top 1000 since the 2000s, and while both are currently taking a break from the charts, Yair in particular is quietly gathering attention. Given to 182 babies in 2023, Yair is simple and distinctive and fits in with the recent interest in off-beat Biblical names.

Zechariah is actually the original Biblical form of the name more often found these days as Zachariah, probably because of the popularity of Zachary. People are going to have trouble getting Zechariah because they won't understand the Zech part. This name, in whatever form, begs to be shortened in the modern world to Zach (or Zac or Zack).
