In page Sarah Vaughan:

"

In 1949, with their finances improving, Vaughan and Treadwell bought a three-story house on 21 Avon Avenue in Newark, occupying the top floor during their increasingly rare off-hours at home and moving Vaughan's parents to the lower two floors. However, business pressures and personality conflicts led to a cooling in Treadwell and Vaughan's relationship. Treadwell hired a road manager to handle her touring needs and opened a management office in Manhattan so he could work with other clients.[citation needed]
