Who was the first person to be a U.S flagmarker?

The first person recognized as a U.S. flag marker is often considered to be Francis Scott Key, who wrote "The Star-Spangled Banner" during the War of 1812. However, the role of flag marker has evolved, and historically, individuals like Betsy Ross are credited with making the first American flag. It is important to note that the designation of "flag marker" can vary based on context, such as military or ceremonial duties.
