NBC Radio's THE BRIGHTER DAY followed the Dennis family and Draper played the oldest daughter, Liz, from 1949 until 1954, when the show began airing simultaneously on CBS television.
Draper then moved on to the role of Linda Pepper on PEPPER YOUNG'S FAMILY.
She also played Fay Perkins on MA PERKINS among other roles.
Draper had one child, Christopher, in 1951 and did theater productions when possible, but largely made her living doing radio and television commercials for many years after that.
In 1954, she appeared on several episodes of the mystery series INNER SANCTUM.
In 1969, she joined the United Seamen's Service, an organization that provided rest and service clubs for merchant marine sailors around the world.
Draper retired in 1985 in New York City. At various times in her life, Draper was an avid reader, traveler, painter and writer. She loved everything that had to do with the theater.
In 2003, she moved to an independent living community in Salt Lake City. In the fall of 2010, she moved to her son's home in Payson, Utah, and the following spring Margaret settled in a care facility in that same town.
