For those who may not be familiar with Terryville:
Terryville is a hamlet (an unincorporated area) in the northwest part of the Town of Brookhaven, in the north-central part of Suffolk County.
Beginning on the north and moving in a clockwise direction, the Hamlet of Terryville in the Town of Brookhaven is bordered on the north by the Hamlet of Port Jefferson Station; on the east by the Hamlet of Mount Sinai and the Hamlet of Coram; on the south by the Hamlet of Selden and the Hamlet of Centereach; and, on the west by the Hamlet of Centereach and the Hamlet of Setauket-East Setauket.
Terryville is one of those many villages and hamlets on Long Island where none of the places in the community have the hamlet name in their mailing address: places in the Hamlet of Terryville have a "Port Jefferson Station, NY 11776", "Coram, NY 11727" and "Selden, NY 11784" mailing address.
