After Roberta's birth, Aimee boarded a ship bound for the United States, reconnecting with her mother, Mildred, in New York City, who got her a job with the Salvation Army.
Aimee met then married accountant Harold McPherson, who moved his new family to Providence, Rhode Island, where their son and Roberta's half-brother Rolf was born.
After 7 years of traveling throughout North America, Aimee decided to settle in Los Angeles to give both the ministry a home base and Roberta and Rolf stability.
Roberta inherited her mother's "brilliant smile," biographer Daniel Mark Epstein noted in his 1993 book Sister Aimee.
She attempted to fly from New York to Los Angeles for the memorial service at Angelus Temple and Forest Lawn, but was bumped from the flight in Chicago when seats were appropriated for military personnel.
