Molly Malone

Who was  Molly Malone? Her statue is at the end of Graffton Street in Dublin and I know that se was a fishmonger and also, she has her own song, '' Cockles and mussels, alive, alive oh!". Did you hear about her legend? This says that she was a fishmonger by day and part-time prostitute by night. But, other people say that  there is no evidence that Molly was actually a real woman who lived in Dublin. Do you know who Molly Malone was really?If yoy have an answer, please, tell me something!
