Names with the largest count in their first appearance on the national list

In 1977, 1,117 American girls were named Kizzy.

The year before, the name did not appear in the national baby-name data at all.

Then Roots aired.

Kizzy was the daughter played by Leslie Uggams in Roots, one of the largest television events in American history. (Levar also made a strong debut that year).
