In a land without magic, seeing Snow give birth to Emma would be sufficient. however, that event took place in the EF, there was magic all around, and based on the promo, there was magic involved (as well as a little more practical thievery)

I do think JMo and Ginny look a lot alike, except for the differing hair styles. But I would bet if you put one of Snow's wigs on JMo, she would look strikingly like Ginny. Enough so that we again see the brilliance of the casting for Once. Emma is, imo, Snow's daughter. But there's obviously more to the story that what we already know.
