Betsy Ross, is widely recognized and given credit by many vexillologists as an important designer of the Original American Flag. However, with the passage of time, information and stories do often change. On occasion, additional facts are uncovered or there are other renditions of the same story that are contradictory.
According to Wikipedia, this early version of the American flag commonly known as the "Betsy Ross Flag," by the claims of her descendants that Betsy Ross contributed to this design is not accepted by all modern scholars and historiographers. Many American historians believe that Ms. Ross was one of many collaborators working on this historical project. Versions of how the flag came to be are presented in various attached links.
Therefore you can debate these facts while cooking on the grill, drinking your favorite libations, watching sports or viewing a spectacular fireworks show lighting up the night!(Remember to bring your pets inside. Most pets are scared of those loud noises)
Happy 4th of July!
