Doctor (Providence)

An unidentified doctor was commissioned by the Royal Navy to study maritime sickness in 1754.

While onboard the Providence as a passenger, he served as the ship's doctor, tending to the sick. It was during this time that he met Haytham Kenway, who inquired about his function on the ship and later on the possibilities of a mutiny. To this the doctor replied that he was too busy to know much and directed Kenway towards James Fairweather.
