Highly doubtful Penny's surname was accidently released alongside someone known only by that same surname.

Qrow is related to Yang and Ruby as he's there uncle but has known them since they were childhood as proven by both his taking Ruby under his wing and rescuing both of them from the beowolves in the grey forest. He also works alongside there farther so if he had a daughter I think Ruby would have recognise her (being there cousin and all) when she bumped into Emerald, Cinder and Mercury and saw her face.
