Her parents separated shortly after her birth
You may not know, one of the interesting facts about Nancy Reagan. Nancy Davis Reagan was born in New York City on July 6, 1921, as the only child of Kenneth Seymour Robbins and Edith Prescott Luckett. Her parents separated shortly after her birth. After their divorce, Edith pursued her acting career and eventually placed Nancy, her two-year-old daughter, in the care of her sister and brother-in-law, Virginia and Audley Gailbraith in Bethesda, Maryland. Nancy spent the next six years with the Gailbraiths.
Edith Luckett remarried in 1929 to Loyal Edward Davis, a prominent Chicago, Illinois neurosurgeon. Nancy and her mother reunited in Chicago, where she went to school and grew into a young woman. Dr. Davis, who died on August 19, 1982, was Professor Emeritus at Northwestern University after more than 30 years as Professor of Surgery there. Edith Luckett Davis went on to work for a number of charitable organizations. Davis's retirement home in Phoenix, Arizona, was where she died on October 26, 1987.
Nancy Reagan had a close relationship with her stepfather and regarded him as her father. Nancy was formally adopted by Loyal Davis when she was a teenager. At this point, Anne Francis Robbins legally changed her name to Nancy Davis.
