I've just looked at Wikipedia and this is what it said:
"Bob's full name is Hrothbert of Bainbridge. A powerful sorcerer, he died in 900 A. D., apparently in England. During his career he authored many grimoires, one of which fell into the hand of Justin Morningway, Harry's uncle. As Harry Dresden put it, there was "some pretty nasty stuff in there," including something called a "Doom Box." Harry burned Justin's copy after it came into his possession (episode 101, "Birds of a Feather"). During his life, Hrothbert fell in love with a woman, another skilled wizard (sorceress), by the name of Winifred. When she was tragically killed, he used black magic to resurrect her. For this he was condemned by the High Council to be a ghost trapped within his own skull for all eternity, unable to interact with the world in any physical way. According to the Morningway-doppelgänger, the story of Hrothbert and Winifred is legendary in some countries. Bob is still sensitive about the subject (episodes 106, "Soul Beneficiary;" 110, "What About Bob?")."
"Harry has since made a way for himself in Chicago, straddling the world of the everyday and the supernatural by acting as a private investigator and consultant for the Chicago Police Department on seemingly unexplainable cases, and Bob is his secret weapon in this. Not only does Bob contain a wealth of knowledge gleaned from his own wizardly expertise, the ghost has accumulated centuries of experience since being tied to his skull. In addition, Bob can take on the appearance of people given a piece of their personage, an ability that has proven essential to the happy resolution of several cases (episodes 103, "Hair of the Dog;" 104, "Rules of Engagements"). The ghostly wizard can also write in the air in glowing letters (episodes 101, "Birds of a Feather;" 106, "Soul Beneficiary")."
I vote we ignore it and continue on with Caspian making Bob. It looks like all this wasn't revealed until over 100 episodes in anyway.
