Charlot married a close friend of O'Higgins, Dorothy Day, an artist who had also grown up in Salt Lake City. Her family was Mormon but later left the church. Her dark skin and brown eyes had long left her feeling uncomfortable in blond, blue-eyed Salt Lake society; she recalled that one day some American Indians came to her door and she saw people who looked like herself for the first time, and connected with them. At age twenty, Dorothy had changed her name to Zohmah and traveled to Mexico. She got involved in the Mexican art movement of the 1920s and 30s, and became close friends with young Mexican and American artists, such as Charlot and O'Higgins, in the circle of Mexican muralist Diego Rivera.
