(Welcome to mystery week! This is the first of 5 posts featuring baby names that saw sudden popularity increases that I can’t quite figure out. Maybe you guys can help?)
In 1980, over 100 baby girls were suddenly given the name Sumiko (or some variant thereof):
**Debuted on the SSA’s baby name list in 1980.
What prompted the Sumiko spike? I’m not sure.
The only possibility I’ve come up with so far is a minor character from The Young and The Restless named Sumiko. According to various soap opera websites, Sumiko was a cult leader (!) who began appearing on the show in early 1980.
Do you have any other ideas?
