2019 Sponsorship

Making a difference at your museum

Dear Friends, 

Would you kindly consider being a Southold Historical Society Sponsor?  We have many enriching projects underway! Our team is continuing its focus on improving its historical collections and increasing its emphasis on community involvement - both of which ensure our longevity and ability to carry out our mission of preserving and sharing our local history. 


Specifically, your Sponsorship will help us to achieve at least the following planned programs and events:

  • Historical Lecture Series – all year

  • Ice Cream Social in August  - returning after a few years’ absence

  • Seasonal exhibitions at the Lighthouse Museum and Museum Complex

  • Candlelight Tour in November – a community favorite

  • Refurbishment of permanent exhibits 

Thank you for your consideration and support.

Fundraising Chair                  Executive Director

The generosity of Southold Historical Society Sponsors helps us hold community favorites like our Annual Candlelight Tour!

Event Sponsors: Receive two tickets to the Summer Social on July 14.  Your name will be prominently displayed on sponsor listings throughout the year.  The Society Board has pledged to carefully control expenditures so that maximum benefit of this fundraising goes directly to supporting the Society’s programming and events.


Business Sponsors: With so many means of communication, the Society will be displaying the names of Business Sponsors in e-mails, on our website, on posted signs and on printed programs at select events and via verbal recognition when appropriate.
