Though no-one is sure of exactly how old Robin de Noir is, he is probably around the age of 16 to 18, probably born in around 1860 to 1863, where his unidentified Mother died, supposedly, from giving birth to him or due to illness.
Son of Coeur de Noir and his unknown Mother, younger brother of Loveday. He has a band of De Noir clan members that he is seen with on various expeditions in the woods - they seem to by his 'clique' or followers, as he seems to be something of a leader to them, however he is initially not respected by his father's people. Whether this is due to the identity of his father (the head of the house) or if they genuinely like him, is unknown. This young man has roamed the forest surrounding Sir Benjamin Merryweather's home his entire life.
(Theoretically the film is set in 1840, but on the tomb of Maria's mother it says that she died in 1874)
