Help with genealogy(Kievian Gediminids)

[Albrecht]

Who is this woman? I need her to proceed with my work.

I cant find her in any genealogies of the kievian Gediminids. As far as I know she is supposed to be a daughter of Olelko Volodymyrovych aka Alexander Volodymyrovych.

PS: Just added her as a bastard. Probably wont affect gameplay very much.

If you want the same dynasty with that person, bastardy won’t help too much because a new line will be created for her descendants.
