Isaiah
Meaning
“God is salvation; one of the most beloved names in Black American families for generations”

The story
Isaiah is one of the great names of the Hebrew Bible: Yeshayahu, God is salvation, the prophet whose book gave scripture some of its most soaring poetry, the swords beaten into plowshares, the voice crying in the wilderness. For all that weight, the name stayed surprisingly quiet in American records for most of the twentieth century. Its climb began in the 1970s and built steadily decade over decade, and it has long been especially beloved in Black American families, where the prophets' names carry generations of church and memory. By the 2000s Isaiah had become a mainstay, peaking in the 2010s and easing only slightly since. It is that rare combination: a name as old as scripture that still feels like it belongs to this moment, strong in the mouth and gentle at the finish.
