Final answer:
The memoir likely features historical figures from the militia or describes unnamed characters based on their roles or physical descriptions. Specific characters like John, Mary, George, or Susan are not typically found in historical memoirs of military context.
Step-by-step explanation:
The characters in the memoir "A Sergeant from the Militia" would most likely be historical figures or unnamed individuals rather than fictitious characters such as John, Mary, George, or Susan. The memoir could potentially mention historical military figures like General George Washington, Brigadier General Daniel Morgan, Major Benedict Arnold, or Major General Benjamin Lincoln, as these are actual historical characters associated with a militia context. It's also possible that the memoir does not mention any characters by name, only describing the positions they held or the roles they played within the militia. Without a specific title to refer to, it is challenging to provide the names of characters from the memoir as they might not be explicitly stated.
The provided information lists characters from what appears to be a different work, possibly a play or another book involving a county attorney, a sheriff, a farmer, and their respective spouses. There are also nine men who appear to be militia members, some of whom are described by physical traits or attire but not named.
