Purpose of Miller Farm:


“To preserve the cultural and historical integrity of The Miller Conservation Farm as a place to afford scientific research, develop conservation education, demonstrate conservation farming practices, and emphasize the conservation and preservation of trees and wildlife.” 


This purpose was established by the late Maynard and Gladys Stonebraker, who gifted the 80 acre farm to Heidelberg University (Maynard’s Alma mater) upon his death. It remains as the perpetual deed of the property since it’s donation to Seneca Conservation District in 1996 from Heidelberg University. Many changes have been made to Miller Farm in order to better fulfill the purpose of the farm and allow the public to access its many treasures.



History of Miller Farm:

Maynard and his wife Gladys, wanted the property to be a memorial to Sidney and Deloria Miller, who adopted Maynard when he was a small boy. The name Miller Conservation Farm was selected to be the future title of this place known locally as “The Stonebraker Farm” where Maynard lived, worked, and played. Many neighbors remember ice skating on the ponds, catching fish, buying apples, and simply visiting to chat with Maynard & Gladys. However, Maynard made it clear he wanted the future generations to remember what the Miller’s did for him and two other orphans, not what the Stonebraker’s did.

While the signs and stories of Maynard’s orchards, tree plantings, and sketch a rough drawing of what the farm used to be, it is through his recently found and transcribed journals that paint the real picture of what the farm looked like during his lifetime. We extended our special thanks to John Crumrine who saw the value in an old box of books. He took the time to read, sift, and analyze the content of Maynard’s journals and “jottings” to help preserve Maynard’s thoughts and experiences!

If any friend, neighbor or colleague of Maynard or Gladys Stonebraker has any memories of the couple or property, we at Seneca Conservation District would be very grateful of your time to share your memories by writing them down for future preservation.


Future of Miller Farm:


With the construction and dedication of the Outdoor Service Center in 2012, the Miller Conservation Farm now has a meeting place for all-seasons and has diversified the extent of activities that can occur at the farm. Storage for equipment and supplies and additional meeting space completed the floor plan of the new building. Many donors, grants. and volunteer hours were secured and given to complete this project.

The future of the Miller Farm is bright with many events and partnership opportunities! We want to focus on sharing this hidden Seneca County treasure with more people but to do that we need your help. Please share this info, attend an event, bring a child to fish, hike, or just take a drive to visit the beautiful place that is yours to enjoy, thanks to Maynard & Gladys Stonebraker.

If you have visited, loved it and want to support Miller Farm for the future, please consider giving a donation of your time, equipment, or monetary resources. Contact the office to discuss our customized giving and volunteer opportunities.
