Except that King Richard the Lionheart, and his younger brother Prince John - later known as King John - were real people.

Besides, I have a feeling that OUaT's Robin Hood originates from Camelot. If you look closely at King Arthur's armor, specifically the belt, there is a lion that looks exactly like Robin's tattoo.
