Still, the most widely held opinion is that the "lady in grey" is actually the ghost of Louise Carpenter, the daughter of the library's founder. Louise once sued the library's Board of Trustees, claiming that her father was "of unsound mind and was unduly influenced in establishing [Willard] Library." She lost the suit and, as a result, her claim to any of the library's property. After her death, her spirit returned to the place that caused her so much grief during her life: Willard Library. Those who subscribe to this opinion say that she will continue to haunt the library until the property and its holdings are turned back over to the living heirs of the Willard Carpenter family.
