Fiction. Just because the names Mary and George are very common and could be used in a made - up story easily. There's no specific information given to suggest they are real, so by default, I'll assume they are fictional characters in a story that we don't know about yet.
If it's a fairy - tale, then they are likely fiction. Fairy - tales are full of made - up characters, and Mary and George could be two more added to the list. For example, in a fairy - tale about a magical forest, Mary could be a lost girl and George a friendly wizard, which are clearly fictional elements.
In many romance novels, Mary Queen of Scots is often a figure of great allure. Some aspects are based on fact, like her royalty and the political intrigue surrounding her. However, much is fictionalized for the sake of a good romance story. For example, her relationships might be exaggerated or her character's emotions might be portrayed in a more modern - feeling way to appeal to readers. In reality, her life was filled with political strife and danger, but in romance novels, these elements are sometimes blended with love stories that may or may not have had any basis in historical fact.
I'm not sure. It depends on the context and the source of the story. Sometimes stories like this can be based on real events but have fictional elements added.
