Elizabeth Griscom Ross, also known by her second and third married names, Ashburn and Claypoole, was an American upholsterer who was credited by her relatives in 1870 with making the second official U.S. flag, accordingly known as the Betsy Ross flag. Though most historians dismiss the story, Ross family tradition holds that General George Washington, commander-in-chief of the Continental Army and two members of a congressional committee—Robert Morris and George Ross—visited Mrs. Ross in 1776. Mrs. Ross convinced George Washington to change the shape of the stars in a sketch of a flag he showed her from six-pointed to five-pointed by demonstrating that it was easier and speedier to cut the latter. However, there is no archival evidence or other recorded verbal tradition to substantiate this story of the first U.S. flag. It appears that the story first surfaced in the writings of her grandson in the 1870s, with no mention or documentation in earlier decades.

The national flag of the United States, often referred to as the American flag or the U.S. flag, consists of thirteen equal horizontal stripes of red alternating with white, with a blue rectangle in the canton, referred to as the union and bearing fifty small, white, five-pointed stars arranged in nine offset horizontal rows, where rows of six stars alternate with rows of five stars. The 50 stars on the flag represent the 50 U.S. states, and the 13 stripes represent the thirteen British colonies that declared independence from Great Britain, which they went on to secure by their victory in the American Revolutionary War.
