You can find out where your father lived more directly. The telephone books and city directories from NYC still exist for the first half of the 20th century, and are at the New-York Historical Society and the New York Public Library. The family will be listed in the telephone book only if they had a telephone, but the city directory should list every family. Then, if you can find the address of the family in 1930, 1920, 1910, and so forth, the notebooks carried by the US census takers still exist, and would list every person living in the household, with some data about them. These are on microfilm in the regional branches of the National Archive -- in NYC, it's on Varick street -- and in the NYPL. The notebooks from the 1940 census are sealed, and won't be released for another 10 years.
