Who is Daniel Belasco from Hell House and what is their importance?

Son of Emeric Belasco, Daniel was drawn into the debauchery at Hell House as a young man, and never developed the strength to leave the atmosphere his father created. He was found still chained to a wall hidden in the wine cellar, having died there after being buried alive many years earlier. Many of the nasty manifestations are at first attributed to Daniel, but it is later discovered that every haunting in the house was perpetrated by Emeric Belasco himself. Florence finds Daniel's identity in a bible in the chapel that lists his birth and then finally uncovers his remains, and takes them from the house that he may rest in peace. Born November 4th, 1903, his birth is announced in a bible that sits on the altar in the chapel.
