Mine did the same. I am following James Harvey who John Alexander is his father. Which John I don't know. From what I am told it I have records of them going way back from there. I am probably like you. I know the ending of the story I just don't know the beginning. I inherited my list from a step-uncle and I am all over the place. Collecting books, cleaning out duplicates and trying to figure out what happened as it sounds like you are doing the same.
