I see it like this. Lily was already pregnant with her second 
child (it is slightly over a year between Harry and Ginny so it 
is biologically possible), when they found out about the Prophecy 
and need to hide. They've agreed to hide Ginny with Weasleys' 
(no, sorry, their anti-girl-curse, if there was a one, has not 
been broken then, and yes it helped Ginny was a natural redhead 
after her mother), which they did slightly after her postpartum 
period (that is after September 22nd). All Weasley boys were 
memory charmed to have included their Mum being pregnant again 
(which, frankly, was not that difficult charm to make, because 
everybody remembers her being pregnant all the time ;)). Then 
Potters started to work on preparing place for Harry with 
Dursleys, but they have never managed to finish it and they never 
told Vernon & Petunia, before they were killed on October 31st. 
Which was the reason why Dumbledore put Harry with Dursleys (he 
actually never really understood the mechanics of those blood 
wards, because they were Lilly's unfinished invention, or 
something).

These two will find out only when told in Harry's fifth or sixth 
year by Dumbledore, who sees a danger of upcoming incest.

Now, it gives us a nice setup for non-Hinny ship which doesn't 
need anybody's bashing. Or even Ron/Ginny ship, if anybody cares 
about that (but that's not probable, due to the `Westermarck 
effect`_).

What do you think? Is there such a fic based on something 
similar?
