Hamnet Shakespeare appears as a character in Gaiman's The Sandman, in "A midsummer's night dream", and then in The books of magic, in "Book III: The Land of Summer's Twilight". In "Midsummer's", queen Titania takes a liking to the boy, and in "Summer's" we see that he has somehow ended up as one of her servants.
Is his story expanded in other comics (most likely not Gaiman's)?
I am not familiar with the follow-up series of "The books of magic", and couldn't locate any additional information one way or the other online. [Edited to add: To clarify, I am asking about the story of the fictional character, not about the real Hamnet.]
