Mary Norton wasn’t shy about dressing in sequins from head to toe. She would have been the center of attention in this dress, glittering in brand new electric lighting. As one of Millionaires’ Row’s prominent residents and the daughter of former Mayor William B. Castle, Mary’s life was filled with parties and family gatherings, both intimate and elaborate. John Hay described her 1876 wedding to David Z. Norton, for which “the whole village came together,” enjoying a wedding reception at the family’s home for hundreds of guests, with dancing, food, and merry-making.
