Betsy Ross flag attribution

The Betsy Ross House at 239 Arch Street is promoted as the place where Betsy Ross purportedly sewed the first American flag in 1776. The claim originates from a family account published decades after the Revolution and is debated by historians because contemporary documentary evidence tying Ross to the first flag is lacking. The site operates as a house museum interpreting both the Ross story and the broader history of 18th-century Philadelphia.
