Some Lore Stuff

Hey, I recently bought bloodborne not that long ago and I got super into it, especially all the environmental storytelling and lore stuff etc. I know the game has been out for awhile so I wanted to get permission from the greater part of the community before I go spewing theories that have already been proven/disproven. So with that aside, has has the possibility of Ebritas being Rom the spider's daughter ever been fleshed out?

Btw I have yet to beat the game and don't have the DLC.
