As I'm writing my story, I came across my family's death certificates. I realized that the causes of their deaths form a pattern. I made up an excel spreadsheet so that I could create a Cause of Death List. I listed as many ancestors that I could find who had a death certificate or a death notice that listed cause of death. I am going to include this list in my book. It's important to know if certain diseases run in the family. For my family, it's cancer and heart disease.
