Membership – Please Join Us!

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

For more information: What We Do and How You Can Get Involved

Your membership provides essential support for the Society's efforts to preserve our past through the continuation of our public programs on local history, the publication of our highly-regarded Tredyffrin Easttown History Quarterly, the maintenance and expansion of our website and our written & photographic archives, and our various community outreach projects. Annual membership entitles you to receive by mail one year of issues of the History Quarterly, featuring full-length articles on local history and other valuable news. Members are also eligible to vote in our elections, and participate in special members-only activities.

Annual membership options are:

  • Household ($50) – Covers an individual adult or family living at the same address.
  • Patron ($150 and above) – Provides much-needed additional support for the Society that is greatly appreciated.

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

Our Tredyffrin Easttown Historical Society Membership Application is available in a printer-friendly format (PDF – requires Adobe Acrobat Reader or equivalent). The form can be filled out electronically and then printed, or you can print it and then fill it out by hand if you prefer. In either case, we encourage you to fill in the application completely, and send it to the specified address along with your check.

Membership Renewal Process


There are several options available for those wishing to renew. You can:

  1. Elect to make an online electronic payment using our secure PayPal service;
  2. Use the postage-paid return envelope that was provided in your renewal mailing;
  3. Download and complete a Membership Application form (see above), print and mail it, along with your check, to the address listed above;
  4. Bring your payment to the next meeting.

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 would 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 most recent payment records we have on file 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.
