text: "bewitched" question:  since serena was samanth's cousin and endora's niece, does that mean (continued) she was uncle author's daughter?  what's your take on it? no.  uncle arthur never married but occasionally had girlfriends.  it had to be from her father's side of the family. by the way.  arthur may have been gay in real life but he was not on the show.  as i said before, he had a few pretty girfriends. serena was not aunt clara's daughter.  she never had any children.
