Dear Taeylor,
Yes, there is a post on Humbert's IMDB page about Jenny's memorial service. So very sad. The individual who posted knew her as a friend-of-a-friend, I guess. He says that Humbert was too ill to attend the memorial service himself.
There is also a long post from the late Craig Hamrick dated 2006 about his interview with Humbert which has yet to be published. Again, very sad, although it sounds as if Humbert's wit was in full form throughout the interview.
Best wishes,
Steve
