History

The area of Lake Grove was settled in the early 18th century along Middle Country Road, which was then part of the Old Kings Highway, originally a Native American footpath. The community's first church building, built in 1818, was the First Congregational Church of New Village. Placed on the National Register of Historic Places in 2002, the building has been preserved and is depicted on the village seal. In 1870, Lake Grove established its first post office, which carried the mail to and from Lakeland station (discontinued in 1883) by horse and wagon. The area was variously called Lakeland, Lakeville, New Village, Ronkonkoma or West Middle Island until it settled on the name Lake Grove in mid-19th century, after the groves of trees near Lake Ronkonkoma.
