Question: Who is Christina Natt Och Dag's maternal grandfather?
Sentence (from "Christina Natt och Dag"): The Royal Council's method of giving queen Christina several foster mothers to avoid her forming an attachment to a single person seems to have been effective: Christina dies not mention her foster mothers directly in her memoirs and does not seem to have formed any attachment to either of them, nor do they seem to have played any part at court after their term in service ended.
Relevant evidence: No
