I was stunned to see Ezra is surging. It was ranked in the 275th to 390th in the late 1800s (aka 19th century). Through the 20th century it reached its least popularity about when I was born. However, recently its surpassed the popularity of a century ago. I hope it reaches new heights. This might be the best way for people to learn how to pronounce my name!
