Since I don't have a lot of information about this particular 'Daddy's Little Girls True Story', it's difficult to say for sure how well - known it is. It could be a hidden gem, known only to those who are directly involved or to a small group of people who have come across it. It might also be a story that has the potential to become more well - known if it gets more exposure in the future, perhaps through word - of - mouth or some form of media promotion.
I'm not sure if it's widely known. It could be a local or a more niche story that hasn't gained mass popularity yet.
It might not be a globally well - known story. There are so many stories out there, and if it hasn't been promoted widely through mainstream media or popular culture, it may be relatively unknown. However, in certain communities or among specific groups, it could be quite well - known and cherished.
