Ok, wait, I don't get how you figure that.  If big-time QH Breeder gets her on Monday, turns around and transfers her to small-time Rescue on Tuesday, that doesn't say diamond in the rough to me.  It says "I really don't want this filly, and I'm not going to advertise her for sale as get of my stallion."  I'm apparently missin' sumthin.

  

What GF said, they could have sent the paperwork into AQHA with 10 transfers with them.
Then the poor horses records would have been really F'd up looking. 
Only way to find out for sure is to contact previous owners.
And yes, she still could be a "diamond in the rough" even with all the transfers.
