In other tales, he was also known as Midge the Miller's son. This is the name used by Howard Pyle in his Merry Adventures of Robin Hood.
In other tales, he was a young boy who befriended the merry men. In several later stories, the name Much is explained by his lacklustre appearance and abilities: his parents continually referred to him as "our son, though he's not much" which was eventually shortened to "Much".
Often it is said he was forced to go into hiding with the outlaws as he had been caught poaching deer on the sheriff's land, an offence which would get the youth hanged. The outlaws rescued the boy from the sheriff's men and later look after him in their hideout in the forest (in the 1991 movie Robin Hood: Prince of Thieves, a character resembling Much in many respects is the young boy named Wulf; another character named "Much the Miller's Son" does appear in the movie, but he has extremely little screen time).
In the earlier tales, however, Much is slightly older and takes a much more physical role; indeed he is a formidable fighter. Much is present from the very earliest Robin Hood ballads, in which he often accompanies Little John on physical journeys and even gets involved in brawls.
In some modern tellings, Much is a female character, initially disguised as (or mistaken for) a boy.
Much played a somewhat minor role in the PC game Conquests of the Longbow: The Legend of Robin Hood where during times when Robin Hood would consult his men for tactical advice, Much would almost always provide the worst plan with the least chance of success. His plans were often crude guesses with no real basis in tactics, which fits well with his character's background, a poor, talentless outlaw of a miller's son.
Much is also a major character in the BBC television series Robin Hood (2006–), but he is no longer a Miller's son — in the second episode, he claims to have no family at all. Instead, he is Robin's former manservant and comrade-in-arms from the Third Crusade, who has been given his freedom as a result of his services there but finds himself outlawed with Robin upon their return home. In this version he is the gang's cook and immensely loyal to Robin, and is often seen to be jealous of the attention Robin gives to others, especially Marian.
