Although, interestingly, they spoke a dialect of French that is different from, for example, Parisian French. And you can tell when a word was borrowed into English from French based on whether it starts with consonant sounds that are from the Norman dialect vs. the Parisian dialect. As an example (IIRC), William is a Norman name, whereas Guillaume is the Parisian version of the same name. Side note: if that kind of stuff is interesting to you, I can highly recommend The History of English podcast.
