I recently read the book, Jane Austen's Names
https://www.amazon.com/Jane-Austens-Names-Riddles-Persons/dp/022641910X. Although I use Richard, I am afraid I can never look at that again in the same light. It gave me a lot of insight into nuances I miss being from the US and not as knowledgeable about British history as JA was. I found it at our local library and found it fascinating. It actually gave me a few plot bunnies for the future. It also makes me believe that Mrs. Bennet was probably Jane, at least in JA's mind. I am not sure I can make that transition in my own mind. However, the book really gave me food for thought.
