The extensive collection of Trimble family antiques and artifacts on display in the Evergreen House Museum speaks to the significance of the 240-year-old farm and reveals the folklife of those who lived it. The house became a museum in 1993 and is now an important part of the Evergreen Heritage Center.
The Evergreen Heritage Center is recognized by the Maryland Historical Trust (1976) and listed on the National Register of Historic Place since 2015. The historical significance of the property is its role in and contribution to the successful settlement of western Allegany County beginning in the late 1700s when it was part of Washington County.
The Trimbles had migrated north from the Shenandoah Valley in the late 1700s and had settled on Federal Hill near Edward Grimes, the first owner of the land that would one day be known as Evergreen. The Trimbles acquired the Winter’s property in 1869 and re-modeled the house to create a large Victorian mansion. They also continued Federal Hill’s history of farming and participated in the region’s booming coal industry.
