Does anyone know what hospitals/homes for unwed mothers existed in Manhattan in 1964?

[quote=252568]I am looking for my sister, who was born on June 19, 1963, I believe in Lenox Hill Hospital. I just learned that my mother was in a home for unwed mothers in Brooklyn (?) but maybe that was Manhattan? My mother's name was Doris Rabidoux. Does anyone have any idea of how I'd find the records of her adoption, or even the home for unwed mothers that my mother would have been in, at that time? Thank you so much, Lisa FInnHi Lisa… I was born in manhatten, born 06/19/1963…. Birth surname Rabidoux.. before changed to adoptive parents.. could I be ur sister?Thanks ( birth name..
