I think Betsy Ross  made the american flag  because it talks about her sewing it and her grandson told her story

Betsy Ross made the American flag during the revolutionary war

Betsy Ross sewed the first flag 1776

her family died

Betsy Ross                                                                                                   George hired Betsy

British thought George Washington was surrendering

The legend is based on Ross’s grandson

There is no evidence that Betsy made American flag
