Is it illegal for a child to use another last/not birth name in Pennsylvania? - legal name change pennsylvania

My daughter has raised the man since birth. She used her name, the name is not on his birth certificate. We are in transition. But this is only a beginner in me and I hope we have done nothing wrong. His father refused, when she was born, and not heard from him in almost 16 years. Well, I'm afraid I'm sad when they publish the legal name change.
