The process of choosing a name for a newborn can be fun. But it can also be stressful. Some parents are lucky to know the name early in the pregnancy or even before, while others take much longer and decide the day they leave the hospital.

Sometimes it’s hard to pick a name. There are too many possible influences – from pop culture to family history and what’s trending.

The most popular boy’s name in Illinois in 2020 was Noah. Noah is derived from the Hebrew name Noach, meaning “rest, repose.”
