Let's Talk About Historical Accuracy and RP
General Discussion
I think this is an extremely important topic and issue and I thank you for putting it front and center. For me, historical accuracy is essential if I am writing about--or speaking as--as a real person who walked the face of the earth at some point.
For a fictional character existing in a real period of history and having contact with real historical figures, historical plausability is key.
For example, Lorsagne de Sade is a fictional character, but the events of her birth, her character, and her life (which will continue to unfold) is entirely plausible (I hope) and based on study of her times and her "real" family members. This kind of character development takes time, but is the appeal of RP to me and I use it as an adjunct to my RL story creation and narrative development.
When all goes well, I find my SL fictional characters that exist in real historical timeframes start to speak and act for themselves; I am simply the typist who shuts up and lets them talk and interact. It's the exact same mechanism as what happens in RL when you create a successful literary character and it's enormously satisfying.
So, I spend a lot of time working on the back stories for each character (I am not nearly as adept as making sure their clothes are correct!) because it can set the stage for RP to come alive and take my characters--both in SL and RL works of non-fiction and fiction--down paths I never would have envisioned.
Historical figures -- such as Mary Delany -- are both harder and easier to portray. If great deal of biographical information exists about that character it's useful to consult, but I always go back to my roots: consult the primary documents. Read and understand the context and the times in which the person lived and approach the character as a biographer and a historian. Be careful not to cast your interpretation in today's times...that way lies madness and a real disservice to the person you are "pretending" to be.
I'm really looking foward to learning from others with an interest in RP!
