Mary Pickersgill and her daughter Caroline sew the American flag, which measured 30 by 42 feet. That flag flew over Fort McHenry during the War of 1812 ( or the Second War of Independence ). Mary, her daughter Caroline, her 2 nieces and a servant girl cut the stars and stripes, all by hand ( it was before the invention of the sew machine ). That flag inspired Francis Scott Key to write a poem " Defence of Fort M`Henry ". The combination of Key`s poem and Smith`s music became known as a song "The Star-Spangled Banner". This song was adopted as a national anthem of the United States in 1931. Answer: Mary Pickersgill.
