In the bio it says "His mother had been a Pomeranian lady whose '''first name and precise origin is not known''' to us, but who is indicated to have come from the ducal family of Pomerelia." Wouldn't it be better if his mothers profile, Hedvig Svantepolks de Gdańsk, of Danzig, reflects this? If there isn't any sources that supports who the unknown mother's parents are, we should remove her parents and let the tree reflect what the sources says. On the other hand, if there are sources that supports that Svantepolks grandfather is Swietopelk II, Duke of Pomerania, we need to change Svantepolks bio to make it less contradictory.
