As an employee of the British East India Company, O'Donnell lived in India for 16 years. Around 1780, he captained the ship Pallas from China to Baltimore, bringing with him plenty of exotic goods.

In 1786, O'Donnell purchased 11 acres of land in Baltimore, which eventually grew to more than 1,900 acres. O'Donnell named his plantation Canton, which is what English speakers at the time called the Chinese port city of Guangzhou.

On his plantation, O'Donnell held 36 enslaved people.

O'Donnell had seven children with his wife Sarah Chew Elliott. It is believed only one, Elliot, returned to his father's native Ireland to study at Trinity College Dublin.

Captain John O’Donnell died in October 1805; at the time, he was one of the wealthiest men in the US.
