Join local historian and author Susan Soderberg for “Treason! How Local Leaders Helped Launch the American Revolution.” It’s Montgomery History’s monthly Tuesday Talk, held at the historic Beall-Dawson Museum in Rockville. The presentation will include the Repudiation Act of 1765, the Hungerford Resolves of 1774 and what led the citizens of what is now Montgomery County into an armed revolt against Great Britain.
