This fits quite nicely with my own theory:

Do we know Ginny's birthday?  Perhaps Their mother was staying with 
the Weasleys right after the birth of her daughter, while their 
father was off working for the order.  Maybe she too was killed by 
LV, or died during childbirth, leaving the Weasleys to care for their 
3 children - Fred, George and Ginny.  Remember Molly says "that's the 
whole family" before Ginny even has a chance of becoming a prefect.

I believe Charlie was described as resembling the twins, while Bill 
resembled Percy and Ron - so maybe Charlie is a Prewett too.

Remember also that Ginny reacted similarly to Harry when she was up 
close to the Dementors (shaking in the corner, on the train).  I 
don't think her experience in CoS would have brought that about, so 
maybe she witnessed something happening to her parents as well.
