Familysearch.org has more records for the 1890 NYC Police Census than does Ancestry. Each individual is listed separately but a check of all Weinblatts in NYC on that census shows all of the family members except Ida and Isaac listed in vol. 231, p. 129. In addition, there is a child Rose age 3 listed as well. Louis is listed as Hyman; otherwise the names match.
I had no luck finding a ship's manifest for any of the US ports.
