Edit 2: It also explains why in (Winter Knight?) the Summer crone told Harry that the Winter crone liked him. It would also explain why no mention has been made of Ebenezer's wife, Harry's grandmother. Surely at some point  Harry would be like "tell me about grandma." Maybe (this is kind of out there) Eb has the blackstaff because he took it from grandma when he split.
