When the village was incorporated in 1931, it consisted of a long, narrow tract of land that was centered along Cedar Swamp Road (Route 107). In the 1950s, the northern portion of the unincorporated area then known as Wheatley Hills was annexed and incorporated into the village, approximately doubling the village's area to its present 2,650 acres (1,070 ha).
When the town of Oyster Bay purchased what is now Brookville from the Matinecocks in the mid-17th century, the area was known as Suco's Wigwam.
