Some books suggest that the search for her birth father was ongoing in Marilyn's life others that her mother first revealed a photo of him to her daughter on her fifth birthday. It turns that due to a DNA test in which strand's of Marilyn's hair from her mortician and the saliva of a great grand-daughter of a man named Charles Stanley Gifford are a match. Gifford was for a time a supervisor at the company where Marilyn's mother was a film cutter, Consolidated fims.
