Located mostly in the Town of Oyster Bay with a small section in the Town of Hempstead, Lusum was originally part of the Robert Williams Plantation. At the turn of the 17th century many of the English settlers became Quakers and renamed the area Jericho. A post office was established in 1802, a cider mill in the mid-19th century, and as the population increased, schools, infrastructure and the necessary suburban lifestyle services and amenities started to arrive and expand. Today, the “downtown” streets are lined with great restaurants and shops. Additional shopping, dining, and entertainment options are conveniently accessible for Jericho residents in nearby Hicksville, Roslyn, and Woodbury. Jericho, while landlocked, is less than twenty minutes from several public beaches. The Long Island Railroad and the Long Island Expressway make the < 30 mile trip to New York City quick and convenient. To this day, Jericho still maintains a number of historic buildings and homes and preserved many of its open park-like spaces. It is also home to The Meadowbrook Golf Club which is a private club.
To the west is the extremely affluent neighborhood of Old Westbury which in addition to high value homes and estates includes three university campuses and two exclusive country clubs in its village: Glen Oaks and Old Westbury.
