The Moriches area used to be comprised of many large estates. According to The Illustrated History of the Moriches Bay Area by Van and Mary Field, the largest in Center Moriches was undoubtedly the Masury Estate located between West Senix (Mud) Creek and the Forge River.
John W. Masury made his fortune manufacturing paint. He invented and patented several paint industry innovations, including a water cooled method for grinding pigments and the familiar lip closure on paint cans (dripless paint can). In the late 1800s, J. W. Masury bought large areas in and around Center Moriches.
