Correct me if I'm wrong but due to the recent reveal that Faith had survived birth, William is technically Faith's half brother. That would make her children Jane and Fanny, William's nieces. So when he slept with Jane in season 6 or 7 at the brothel, she was actually his niece. I'm assuming this is a continuity error that went unnoticed and also a reason why no one bothered to tell him that he was Fanny's uncle.

If not, then my guy William just can't catch a break when it comes to women and the frequent "oh guess what" moments he had the last two seasons.
