62 oh, about the dad problems. His dad was the first vampire on Innistrad, by making a deal with a demon if I remember correctly. He wanted everyone to be super powerful and taught that being a vampire would be the way to be that.
Everyone for obvious reasons rejected the offer and thus he turned Sorin into one to try and prove something. I'm not sure what happened after him, I wouldn't be surprised if Sorin killed him afterwards but not sure about that.
Also, this is all going from memory thus there might be errors in it.
