Edward Dwan was a sergeant of marines in the 6th (Plymouth) Company when he arrived at Sydney with his wife and baby son aboard the Charlotte in January 1788 as part of the First Fleet. He served with Captain James Campbell's Company at Port Jackson and was listed in court records as quarter master sergeant. Two more sons were born in 1789 and 1791.
The family left the colony for England in the Gorgon in December 1791. The two youngest sons died during the voyage.
