Only Sapkowski knows, but he isn't talking, nor did he do anything like connect every detail.

He didn't write anything about the subsequent history of the Northern Kingdoms. Thus we have to use a combination of what he did write, what we know about a world that he clearly drew on when writing about his world, and what poor imagination in comparison to his we can bring to the party.

Alternatively, we could say that because Sapkowski gave no answer to the question, we should pull a Wittgenstein and refrain from asking. But that's no fun.

Do you remember Deidre Ademeyn? She is a character in The Witcher module "The Price of Neutrality" who had the great misfortune of being born during a total eclipse (SPOILER: She became Eskel's "Unexpected Child" as you may know):





Maybe Ciri was created after Deidre character's model... I would like something like that. ›››
