Elizabeth Griscom "Betsy" Ross, née Griscom, also known by her second and third married names, Ashburn and Claypoole, is widely credited with making the first American flag. According to family tradition, upon a visit from General George Washington, commander-in-chief of the Continental Army, in 1776, Ross convinced George Washington to change the shape of the stars he had sketched for the flag 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 American flag, and it appears that the story first surfaced in the writings of her grandson in the 1870s, with no mention or documentation in earlier decades.
