19-28 Centennial Oak / An Ohio Suffragist Legacy
Side A: The Newbury Woman Suffrage Political Club, headquartered at Union Chapel, planted the Centennial Oak on July 4, 1876. The White Oak (Quercus alba) was chosen for its endurance, longevity, and beauty. The picnic and planting celebration included speeches, songs, fireworks, and a poem dedicated to the Oak written by local suffragist Anna Green. As the club gained national recognition, it attracted such notable suffragists as Susan B. Anthony and Harriet Taylor Upton as visitors and speakers. A Newbury gathering on August 23, 1919, held to celebrate Ohio’s recent ratification of the 19th Amendment, included suffragists Upton and Frances Jennings Casement. The last living founding member of Newbury’s Woman Suffrage Club, Dr. Julia Porter Green, led a parade from the chapel to Centennial Oak. There she placed a wreath of evergreen and goldenglow upon the tree.
Side B: South Newbury’s Centennial Oak stands west of Route 44 about 350 feet north of Union Chapel. In 1876, the tree was planted on the private property of Darius and Sophia Allen in an effort to protect it from vandalism by those opposed to women’s suffrage. While planting the oak, the Newbury Woman Suffrage Political Club members placed a glass container, encased in concrete, beneath the tree. Preserved within the time capsule was a list of club members, by-laws, poems, and documents celebrating the achievements of their local suffrage campaign. Planted during America’s Centennial celebrations, the oak is protected by a conservation easement in recognition of its longevity and history. It stands as a symbol of the woman who fought for their rights and the impact they made upon Geauga County, Ohio, and the nation.
