Final answer:
The letter was written by John Hughes, who based on the context of his concerns and loyalties was quite likely a British official during the colonial period of American history.
Step-by-step explanation:
The letter was written by John Hughes, and based on the content of the letter, which suggests he is a supporter of British rule and is concerned about the Presbyterian-led opposition to the monarchy, it is reasonable to deduce that John Hughes was a British official.
He expresses dismay at the actions and sentiments against the British Crown by the colonists, who are incensed by what they perceive as unconstitutional acts such as the Stamp Act. Hughes' appeal is for the restoration and preservation of allegiance to Britain, indicating his official role in maintaining the colonial governance under British authority. 4
This aligns with the general sentiment among British officials who saw the colonists' response to the Stamp Act as a threat to British imperial control and the economic interests tied to the colonies.
