So technically she was also in every other teacher's care at Signal...

...and when she said she was nothing until Qrow took her under his wing she clearly meant combatwise.

Also in conversations with Ozpin and Yang she mentions  her parents, specifically their dad - so there clearly is someone other than Qrow in whose 'care' she is, respectively was.

Actually, we don't know whether Signal is a boarding school, don't we? So being at Signal could have meant living at home. The references to 'what would Dad say?' or 'you sound like Dad!' would make sense then.
