The family moved to nearby areas such as Shavertown, Grove City and Trucksville and spent a year in New York City before settling in Tenafly, New Jersey, where she attended Tenafly High School. Ada Enke taught her daughter singing and piano; mother and daughter were members of the Grove City Presbyterian church choir. Adams's grandmother, a seamstress, taught her how to sew. She made her own clothing beginning in the sixth grade and Adams would later have her own designer line of clothing, called Bonham, Inc.
