They had survived so much already — war and dust storms, cancer and poverty, lost eyesight, lost spouses, lost memories — and still went on to find moments of grace inside the corridors of America’s nursing homes. The 51 residents whose stories are told here left behind at least 129 children, 230 grandchildren, 210 great-grandchildren and 41 great-great-grandchildren. Some blame the nursing homes for questionable care. Others say they are enormously grateful for the work of caregivers. Most have put off memorials for when it’s safe to gather again, side by side, and remember the dead.
