The show never mentioned Lois' (or is it Lois's
) middle name. In the comics, it was primarily Joanne, though I think there was a very short stretch where it was Marie. Note I am not a comic book reader. I've just read a lot of discussion on this topic.
The name "Ellen" was used in at least one fanfic I've read, but that name has never been used in any official capacity for her middle name by DC Comics.
