How can I be sure this was, indeed, my Leiser Liebross? The proof is somewhat circumstantial. My Leiser arriving in 1897 indicated he was 37 years old. This Leser in 1895 (two years earlier) shows an age of 35.
We know that Leiser's brother Simon was in Brooklyn as early as 1892: at that time living at 26 Moore Street. In an 1893-4 Brooklyn city directory, Simon is living at 203 Boerum, Brooklyn.  In an 1897-8 city directory, he is at 244 Boerum, Brooklyn.  On this 1895 manifest, Leser states he is going to Brooklyn. No other Liebrosses are listed in any directories in Brooklyn (or in New York City, for that matter).
The 1897 Leiser indicates that he is a merchant. The 1895 Leser says he's a laborer. There is a chance he changed his profession between 1895 and 1897, but, no one was likely to check the occupations claimed by immigrants. And there are studies indicating that the quality of immigrants' occupational reporting was low.  At this point, I have no way to evaluate the two responses to the occupation question or resolve the conflict.
My hunch is that this 1895 trip was a visit by Leiser to the United States either in advance of making a decision to move the family or in preparation for such a move.
