Membership – Please Join Us!

Founded in 1936 as the Tredyffrin Easttown History Club, and reorganized in 2005 as a not-for-profit corporation, the Society celebrated in 2016 its 80th year of researching and teaching the history of historic Tredyffrin and Easttown Townships and Philadelphia's Upper Main Line. The Society extends a membership invitation to all who enjoy exploring the diverse history of this fascinating area.

Your membership supports the Society's efforts to preserve our past through maintenance and expansion of our written and photographic archives, the expansion of our website, and the continuation of our programs on local community history. Annual membership entitles you to receive by mail one year of issues of the Tredyffrin Easttown History Quarterly, featuring full-length articles on local history and other valuable news.

Annual membership dues for 2017 remain $40.00 for an individual adult or family living under the same roof, and $24.00 for students under 18 years of age. Other membership alternatives are described on the application form. Membership at the Patron level provides much needed support for the Society and is greatly appreciated.

Please note that since the Society is a not-for-profit corporation under I.R.S. 501(c)(3), your entire membership fee and any additional contributions to the Tredyffrin Easttown Historical Society are fully tax-deductible to the extent of the law. Please consult your tax advisor for more information.

New Membership Renewal Process

In December 2016, the Society started using a new annual membership renewal process. With more new members joining at various times throughout the year, we realized that it will be better to inform members on a monthly basis that their annual memberships are due for renewal. Instead of relying exclusively on email notifications, we will be sending a renewal notice by mail in the month of the renewal date. We will use the payment records we have on file from 2015–16 to determine the appropriate renewal dates for all current members.

We will continue to mail the History Quarterly to the address that we have on file for our members, and will send the renewal mailing to the same address. To avoid delivery problems, members should make sure to inform us of any address changes.

If you receive a letter but have already recently renewed, you do not need to take further action, unless you need to provide us with updated contact information.
