I don't have enough information to say who they are exactly. They could be ordinary people with an extraordinary story, or they could be well - known in a specific community or area.
I'm not entirely sure who Aubrey Manning specifically is in this context. But he's likely someone who has a significant connection to the story about the Earth. Maybe he's a scientist, an explorer, or a storyteller.
Bradley Manning was a U.S. Army soldier. He leaked a large amount of classified information to WikiLeaks. This act was seen as a major event in terms of government transparency and national security. Manning felt that the public had a right to know certain information that the government was keeping secret, but the U.S. government considered it a serious breach of security.
I'm not sure who 'Pamela Novel' specifically is. It could be an ordinary person with that name, or perhaps it's a name in a very specific context like a small community, a family name, or even a made - up name in a local story.
Pamela in the novel is a very virtuous character. She is constantly tested in difficult situations but always holds on to her moral values. For example, she resists the improper advances of her master firmly, showing great strength of character.
