I believe New York had a whole network of Mental Hospitals throughout the state. On Long Island alone, there were Creedmore in Queens, Pilgrim State and Edgewood (children) in Brentwood, Kings Park in Kings Park and Central Islip in Central Islip. There probably was one in Brooklyn, but I don't know its name.... Have you checked with the state Mental Health Office? I have telephone numbers for the regional office in Brentwood at 1-631-434-5311 or 1-631-434-5333. Hope this helps.... Regards, Grace
