I have an Edith Kuhne, b.1915 in New York Manhattan, with parents there in 1920 and 1930 censuses. Parents Ernest Kuhne 1880-1963, and Katherine (Kitt) Allen 1885 - ?. Ernest was born New York, died Long Island. Katherine was born Newport RI. I don't know if this could be te connection to your Edith Kuhne, but I would like to know if it is.
