What was considered to be a N. Y. accent, a la the Bowry Boys and in some gangster movies of the '30s, is, in reality, Irishism. That " toity toid street " stuff is directly from the Irish immigrants in N.Y.C.! But there have been and are so many different N.Y. accents, that that is NOT all that repsesentative at all. Accents, in N.Y.C. ( and I am referring to all FIVE boroughs ! ) vary from street to street sometimes and from generation to generation. My grandmother's was different from my mother's and my accent ( everyone has one ! ) is such a hodgepodge, because I went to boarding school in Pa., undergrad in N.H., and picked up some things from my Bermudian pals, I hung out with, when we stayed at our home there.
