In my family tree I have only 900 names so far, but only 3 death certificates for cause of death.  A family member currently has multiple issues related to joints/cartilidge which I would love to be able to trace back, but I believe that will be a hard process considering that most of the families shied away from the doctor's office.
If anyone has any idea's, tips about adding a Medical side to the family tree I am all ears.  I know that I can use my military record for anything about me, but then what about the rest of the family.
