That's the name "Tamiko" you're thinking of,
Andrea Lynn , and that other websites may perhaps be getting confused. Tamiko is similar in spelling to
Tamika , but it's a completely different name -- and has been popular in the African American community for at least a couple of generations now.
The feminine "a" ending on Western names isn't a feminine ending at all in Japan.
It is actually the suffix "-ko" (meaning "child") which feminizes a name in Japan. And, of course, the word "
Tami " means "people" in Japanese.
