] It's interesting to me that Darcy was thinking of Mr. Bingley for his sister, because he didn't have nearly the connections and gnereational consequence of the Darcys....what do you think?

I don't quite recall but I don't think Darcy is thinking of marrying his sister to Mr. Bingley. It is only Caroline Bingley who mentions it in a letter to Jane and makes it seem that way.
