Hi all, I'm doing research for a novel and I've come across a real person who I'd love to involve in the novel. She died in 1874 and I want my main character to be a descendant of her. Because she will most likely have real descendants can I do this? The main character isn't based on anyone living but the real person is fairly famous. Would I be able to include her? Also if anyone knows of any good sites I could use to find out what the law says about people in fiction that would be great. Thanks.
