Almanzo, I believe he actually died of heart attack(s). I am not sure he had cancer or anything asbestos related. And if you are trying to remember what he and Laura had (when Rose was a baby) it was diphtheria, the D in DPT (diphtheria, pertussis/whopping cough and tetanus). He had lower body paralysis and weakness (I think for the rest of his life, to some extent) from the diptheria. And I think it was somewhere in that time frame (within a year maybe) that Laura gave birth to their son who only lived a short time.
