When the 1920 census was enumerated, Marian's family lived at 52 Gladstone Avenue in Detroit and her father was the treasurer of the family business. He had also started a real estate development company and was considered one of the most prominent businessmen in the city. Her father died in 1926 at the age of 49, leaving Elsie a widow with five children and expecting a sixth. She married John Frances "Frank" Deacon in 1928 and had one daughter, Marian's half-sister.
By 1930 Marian's new family lived at 772 Chicago Boulevard in Detroit. Frank and Elsie Deacon owned and operated a real estate business. The home was valued at $50,000 and the family had four servants.
