Assuming Ana is indeed Ella's sister and assuming the wand that heals Marian is the Fairy Godmother's

Ana was stilll in the EF when Rumple got the wand

Ana was still in the EF when Robin stole it, because Marian was still alive

So Will and Anna went there after Belle was living with Rumple, so Regina was already the Evil Queen.

It is possible, I guess.
