I can't help but think that maybe Grisha is siblings with Historia's mother. And he was the one who introduced her to HIstoria's father to get into the wall sect thing. Now that he was part of it, he could have gotten access to the outside world, where he met a clan of titan shifters. Maybe that's where he met Carla. They could have live happily there until Grisha wanted to get the power of the shifters. He could stolen it, that would explain why Eren has the Coordinate. As for the Female Eren we saw, maybe at the time Carla had already given birth? And when they ran away, they couldn't bting her with them. It could be that Eren and the woman have some telepathical link.

this is all just speculation tho.

posted this on my tumblr too!~
