This term is found in Book 3, Chapter 1 "Sissy" (hands down, my favorite chapter of the whole book because who doesn't know a real-life version of Anne Anderson?):
She hung up and went over to her weeping mother and her harp relatives.I've tried searching Google and dictionaries, but none of the definitions I found seem correct in this context.Bobbi would deny [Anne's false accusation], so the harp uncle would probably let it go -- unless the harp uncle happened to be very drunk...
The only thing that sort of makes sense to me would be a family member who is physically there with the bereaved for comfort and support in the days surrounding a death.
Anybody able to shed some light on this?
