Cypress Hills has sometimes been thought of as being part of East New York. I would like to correct my western boundary. Cypress Hills starts at the junction of Fulton St, Atlantic Ave & Broadway. This is several blocks west of what I originally told you. The Highland Park area is often considered as part of CH, even thought it is north of Jamaica Ave. The same could be said for City Line which is south of Atlantic.
CH is indeed south of the CH Cemetery, as well as a number of other small cemeteries. Incidentally, it's Cemetery of the Evergreens, not Everglades.
My recollection is that the student population of Lane in those days was evenly mixed between Afro-American, Italian, Irish & German.
No matter how you figure it, East New York is in Brooklyn, not Queens!
