Andrea Yates was a mother who unfortunately drowned her five children. In the context of the 'Andrea Yates and True Hollywood Story', she is the central figure. Her actions were so extreme that they caught national and international attention.
Raven Roth may also be a character who has a mysterious past related to the dark arts. Maybe she was once involved with a group or a situation that had ties to Voldemort, but she has now turned against the dark side. Her knowledge of the dark arts, though dangerous, could be used to help Harry Potter understand his enemies better and find ways to defeat them. This complex backstory would make her a very interesting character in the fanfiction.
Well, there could be her grandfather. He might be the one who taught Andrea how to drive the tractor in the first place and is always there to give her advice when she encounters problems with the tractor.
Since we only have the title, it's hard to determine exactly who Andrea Hines is. She might be a public figure, but then again, she could also be a private individual whose story is being told because of some unique event related to the 'Blitz Attack'. It could be that she is someone who has a particular connection to the events that unfold in the story, whether it's as a central character, a key witness, or someone who has been affected in a major way.
I'm not sure who Randy Roth specifically is without more context. There could be many people named Randy Roth. He could be an ordinary individual, a local figure in a certain community, or perhaps someone known in a specific field like business, arts or sports.
Since I haven't read the fanfic, it's hard to say exactly who Raven Roth is. But based on the title, Raven Roth is the one who breaks Naruto's heart, so could be a character created for this particular fanfic.
