Obituaries and family members can easily hide a key detail in a person's life. According to family members, my great-grandfather died at home. His obituary in the paper indicated he died at home. He did not. After suffering from a series of strokes, the family could no longer take care of him and he was put in a state hospital several counties away where he died a few weeks later. They cared for him at home for years, but were no longer able to towards the end of his life.
That's why it took me forever to locate his death certificate--I was looking in the wrong place.
