Yes, Adeline Watkins did visit Ed Gein. She was a real person who had a relationship with him, though the nature and duration of their relationship are debated. After Gein's arrest, Watkins described him as "good and kind" and said he would occasionally visit her home. They dated on and off, with Watkins initially claiming a 20-year relationship which she later retracted, stating their romantic involvement lasted only about seven months. They reportedly discussed murders and crime during their acquaintance, and Ed Gein even proposed to her in 1955, which she declined. However, Gein never publicly acknowledged her, and Watkins later distanced herself from him after his crimes became known.
