A baby brother for Sophie and Lucas

Ezra has a lot going for it: the strength of its heroic Biblical legacy, its quirky sound, and its fresh but familiar feel.

Old Testament name of a king of Israel, related to the harvest.

This simple, elegant name offers something for many kinds of parents, from writers and history buffs to photographers to Pennsylvania dwellers.
