* The name is incorrect: There may be a slight variation in the spelling or a missing middle name.
* The recipient is not well-documented: Some Medal of Honor recipients have less information available about their lives, especially those from earlier conflicts.
To help me find information, could you please provide:
* Any additional details about Alexander Parker: His branch of service, the war he served in, or any other details about his life.
* The source of information: Where did you hear this name?
With more information, I may be able to locate a potential recipient.
