Uncle Max Goldstein of New York City

Just to give my readers a taste of the puzzle I face in researching a Goldstein family in early 20th century New York City, I share the following image, which is from the 1914 New York City Directory. There are eleven Max Goldsteins who are tailors among the countless men of the name in New York City at that time. I believe the one at h9 2d av (home 9 Second Avenue) is the one I'm looking for, because that was his address in the 1915 New York State Census and the 1920 U.S. Federal Census.
