Elmyra is still alive, despite Aerith not being. So make that two. I know she isn't the biological mother, but don't be smurfing picky, the woman raised her! With that in mind, you could almost add Edea as a surrogate mother...

Yeah we start getting messy when we go with that. Damn near all of them have replacement parents. Cid and his wife in III cared for the kids iirc.

I see the point though. Sucks to be a mom.
