My mother was born in 1920 in KY. She remembers as a child the undertaker would go to the home and embalm the person there. They would be viewed usually for a day and then taken to the church for the funeral. While they were at the home, the person was never left alone. Someone always stayed up all night with the corpse. I remember as a child in the 50's and 60's, people discussing who would stay at the funeral home all night with the body so they would not be left alone until they were buried. Sue
