Thanks, MB. [spoiler]I don't have the almanac, so I didn't know about the family tree. I do remember that Lenore was Quentin's only surviving child. Lenore must have had only one child, a son who became the father of Tom, Chris, and Amy. If Lenore had had a daughter who married a Haskell, then Joe would be a first cousin of the Jennings sibs--and also would have been cursed. I guess the whole Cousin Joe thing had to be dropped as the writers developed the story of Quentin's descendants. But Lenore's son would have been cursed too--and we never hear anything about a Collinsport werewolf in, say, the 1920s or thereabouts.[/spoiler]
And yes, I suppose Angelique had to suffer for what she did to Barnabas. But for me the fun of this story line is watching Nicholas.
