Mrs Umney was the housekeeper of the Canterville castle. She was a bit of an orthodox woman who believed in the ghost that haunted the house. She was taken aback at the disrespectful and matter-of-fact attitude that the Otises adopted towards the blood stain. She was flabbergasted as they proceeded to clean the stain by rubbing at it. Her superstitious character is a foil to the practical nature of the Otis family.
