Anosike is Igbo. A nosi ike = One who sits securely.
In translating this name, we must go beyond the above spelling. It is probably that in a rush to shorten, a few vowels were left out. In “A nosie ike (o di ka uwa amaka)” [When one sits securely, it appears the world is beautiful] we see a more deeper meaning than offered by the popular written version. This is why this compilations favors the more vowel intensive version of Igbo names.
