Some notes and comments on Josiah's Death:

1) Dropsy was our ancestor's term for Edema (swelling), which was usually caused by kidneys or heart disease (especially congestive heart failure).
2) Not Certified means that the death was not attended by a physician or other official who would have treated or verified the disease. The local constable would inquire into these deaths if deemed suspicious.
3) Samuel was very much in demand to witness family events. He was about 16 when he attended and reported his father's death. He also attended and reported his mother's death and he was the witness to John & Sarah Platt's wedding.
