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.
