The Freeport Memorial Library provides free access to the census and other genealogical resources through Ancestry.com.
If you had family living in Freeport in the 1940s and are having trouble accessing the newly released 1940 census, try the Freeport Leader for that decade: www.longislandmemories.org.
The library also has Freeport High School yearbooks from the 1940s in our Long Island Room.
