The North-Evans Chateau aka the Bellevue Chateau, located on the Bremond Block at 710 San Antonio Street, is supposedly haunted by Athalie North, the daughter of Harvey and Catherine. She was a pianist but died young coming back from a music school in Europe. They say she plays at various pianos throughout the house at all hours and her apparition has been seen.

I also found this old photo of what the house originally looked like (view from Nueces Street)
