The Swezey Family


Visit the Swezey family exhibit in the Swezey-Avey House. The Swezey family arrived in Southold in the mid-1600s and in Yaphank in the 1700s. Come learn about the family’s lives into the 20th century, including the lives of Dr. Gilbert Hopkins Swezey and his daughter Dr. Sarah Swezey-Avey, the last Swezey family member to have lived in the house from 1944 to about 1960. To visit, call (631) 775-0735 to make an appointment or email us at info@yaphankhistorical.org to make an appointment.


The Weeks Family Legacy


Yaphank’s most important family, the Weeks, settled in Millville (now Yaphank) in 1828. Portraitist William Sydney Mount was commissioned to paint James Huggins Weeks and his wife Susan Maria, in 1838. See this permanent exhibit at the Swezey-Avey House.


Our Library Collection, searchable by author, title, subject, and date, and our Archives with online Finding Aid, make excellent research tools.
