I am researching a distant relative who first appears in the New York
City phone directory in 1949. I am trying to establish an exact
timeline of her life. Does anyone know when exactly during the course
of each year the directories were updated and how closely they reflect
the date of a person's move. For example, if Ethel was in the 1949
directory, does that mean she had probably moved to NYC in 1948?
Thanks for any light you can shed on this.
