Founding Families Weekend

During Founding Families weekend, at the Museum Complex on June 2-4,2017, a tent will be set up with at least 12 long tables and chairs. Twelve founding families will be identified, and on each table there will be a small bulletin board where family members can leave messages for other family members. Also, these tables will provide an initial meeting place.

Around the perimeter of the tent, there will be a long horizontal display board with a timeline starting in 1640 and ending in 2017. On this timeline, we will be displaying information on all families that call Southold “home”.

Please click here to download and complete this questionnaire. You may print it and and send to the Southold Historical Society, PO Box 1, Southold, NY 11971 by May 10. We will place your completed questionnaire on our timeline. If you are descended from more than one Founding Family, please feel free to make additional sheets.
