Henry Cope purchased 40 acres of land in East Germantown, Pennsylvania in 1852 where he built a home for his growing family. Over the next 70 years, his descendants build 24 houses representing a variety of architectural styles. A portion of this land, now known as the Awbury Arboretum, was left to the City Parks Association in 1916 to protect it from development. The Awbury Arboretum Association Cope family collection, 1791-2011, encompasses several small collections donated by various descendants of the Cope family. It includes correspondence, deeds, financial records, journals, and photographs.
