Betty Washington Chapter, NSDAR, was formed on October 17, 1896, in Lawrence, Kansas. The organizing regent was Mary Lawton Robinson, the niece of Kansas' first governor, Charles Robinson.

The chapter was named to honor the only sister of George Washington, Betty Washington Lewis. Betty Washington was the wife of Colonel Fielding Lewis, who served in the American Revolutionary War. Their home was called Kenmore and is located in Fredericksburg, Virginia.

Among the first members of the chapter was Lucy Pratt Esterbrook, whose father had served in the American Revolutionary War. Mrs. Esterbrook, a "Real Daughter," received a tribute from the National Society; a gold spoon depicting a Colonial woman turning a spinning wheel.

Several "Real Granddaughters" were also charter members and early members of the chapter.

Betty Washington Chapter, NSDAR, members have served DAR, their community, and their nation for over 125 years, seeking to fulfill the organization's mission statement. The mission of the National Society Daughters of the American Revolution is to promote historic preservation, education, and patriotism."
