The Doan Gang roamed Bucks County, Pa., in the 1770s, and were known for exploits that included stealing horses and selling them to the British, robbing the Bucks County treasury, and in general, disrupting the new governments of Pennsylvania, New Jersey, and Maryland. Later romanticized, they were considered both villains and heroes.

Discover their untold stories at the Mercer Museum in Doylestown, Pa., beginning May 4 in a new exhibition, “The Doan Gang: Outlaws of the Revolution.” The museum delves into an immersive history of the  Revolutionary War-era loyalists and a world of espionage, legendary robberies, and mythical lost treasure. Visitors will learn how these outlaws plotted, schemed, and plundered through a divided world in the early days of a new nation, and how their loyalty to British rule in the Colonies sometimes forced their neighbors and friends to choose sides during a time of great political and social unrest.

The Mercer Museum is located at 84 South Pine Street in Doylestown, Pa., and is  open Tuesday through Sunday from 10 a.m. to 5 p.m. Admission is $15 for adults; $13 for ages 65 and up; $10 for students, $8 for youths ages 6-17, and free for children under age 5.

The member preview day is Friday, May 3. This special exhibition is included with museum admission. For more information, visit mercermuseum.org/doanprograms.
