when three members of a secret committee from the Continental Congress came to call upon her. Those representatives, George Washington, Robert Morris, and George Ross, asked her to sew the first flag. This meeting occurred in her home some time late in May 1776. George Washington was then the head of the Continental Army. Robert Morris, an owner of vast amounts of land, was perhaps the wealthiest citizen in the Colonies. Colonel George Ross was a respected Philadelphian and also the uncle of her late husband, John Ross.

Until that time, colonies and militias used many different flags. Some are famous, such as the "Rattlesnake Flag" used by the Continental Navy, with its venomous challenge, "Don't Tread on Me."

Other flags were quite similar to Britain's Union Jack or incorporated elements of it. A picture of the "Grand Union" flag is shown here. This is not surprising. Many colonists considered themselves loyal subjects of Britain — many colonists came from Britain, and King George III ruled over the colonies. On January 1, 1776, the Continental Army was reorganized in accordance with a Congressional resolution which placed American forces under George Washington's control. On that New Year's Day the Continental Army was laying siege to Boston which had been taken over by the British Army. Washington ordered the Grand Union flag hoisted above his base at Prospect Hill "in compliment of the United Colonies." In Boston, on that New Year's Day, the Loyalists (supporters of Britain) had been circulating a recent King George speech, offering the Continental forces favorable terms if they laid down their arms. These Loyalists were convinced that the King's speech had impressed the Continentals into surrendering — as a sign of the Continentals' "surrender," the Loyalists mistook the flying of the Grand Union flag over Prospect Hill as a show of respect to King George. In fact, however, the Continentals knew nothing of the speech until later. Washington wrote in a letter dated January 4, "By this time, I presume, they begin to think it strange we have not made a formal surrender of our lines." Obviously a new flag was needed.
