Call them (the children you have adopted) after their (real) fathers: doing so is more equitable in the sight of God. If you do not know who their fathers are, then (they are) your brothers in religion and your protégés (so observe the duties of brotherhood between you and them). However, there is no blame on you because of the mistakes you may make unintentionally (in naming them), but what your hearts have premeditated (matters greatly). God is All-Forgiving, All-Compassionate.
